1.10.2 - versions FunOres-1.11.x-1.5.1-101 & FunOres-SilentLib-1.10.2-2.0.2-42

This is the config I've ended up with:
funores.txt

Something is not working correctly with the FAVORS option - maybe it's multiplying in the favored places, but not dividing in the unfavored places ? Not sure exactly, only that I'm not getting the result I'm after, which is a tiny amount of ores in most places, and large deposits in others by biome type.

Also a few minor issues in the config in the recipe_extra section, with there being double-ups of recipes for aluminium items, and those doubled up recipes are showing twice in JEI.

Also, if you try and go to the second set of tabs in JEI (the non-vanilla minecraft ones) in creative mode, which should at this point only have the fun ores tab, it crashes with:
crash-2017-03-10_13.09.30-client.txt

Is it only vanilla ores that seem to be affected? It looks like the configs for vanilla ores aren't loading correctly, as the ReplaceExisting option isn't there (you'll want to enable that when I get it fixed). Biome lists are working correctly in the latest version, as far as I can tell, so my guess is you are seeing vanilla oregen.

One way you can test whether FAVORS is working or not is using WIT's advanced mode. It reports the number of veins that should try to spawn in each chunk for the biome. Install WIT, press numpad 4 to toggle advanced mode, place the ore in the biome you are testing, and look at it. It also lists the types of the current biome. Just make sure you are at least 1-2 chunks into the biome, or it might display the wrong biome (it goes by the biome at the center of the chunk, if memory serves).

Aluminium recipe configs are working as intended. I included one for both spellings (aluminium (extra i) and aluminum). Some mods only oredict their ingots to one spelling, so I'm just being thorough.

I'll take a look at the creative tab crash later today. Probably a cross compat issue.
(edit) Oh, JEI tabs. Must learn to read. But the crash still doesn't happen for me in either 1.10.2 or 1.11.

Vanilla vs non-vanilla ! That was exactly the problem. When I went back to the config, it had replaced all the vanilla ore fields with blank ones, and including the B:ReplaceExisting line this time. Not sure what went wrong there. I plugged in my values, ran it again and it looked fine - and it didn't replace the config again, so it's all good.

I can't believe how often I looked at those Aluminum fields and didn't see the different spelling :) Just goes to show that we see what we expect to see.

It definitely still crashes in your inventory when you change tabs. To test the inventory problem further, I removed FunOres and added another mod and it's tab showed up fine. I removed JEI and launched with absolutely nothing but FunOre and SilentLib, and it's still crashing. I'm using forge 1.10.2-12.18.3.2254 if that makes any difference, but I rolled it back to 1.10.2-12.18.3.2185 and it still crashes.

Sorry to have to add even more :) But, I tested some more and it was all good until I got to a Roofed Forest biome. This ought to be considered Forest & Magical biome types, but it appeared to have favoured everything, in particular it looked like it double-favoured Coal, as the biome was almost solid coal - never seen so much in one place before.

This is the config I'm using:
funores.txt

I'm testing on Seed 277249098916529181, vanilla minecraft (with forge, FunOres, SilentLib & WorldStripper, nothing else), and in creative. You start in a Taiga, there's a Plain nearby and a Roofed Forest just past that.

Replicated the crash, it is a creative tab issue. I forgot to switch it to the compat version. Not sure why I couldn't get it to happen before.

I took a look at the roofed forest on that seed (with the config you provided) and didn't see anything out of place. I also have Gems installed, but here's a screenshot:

Seems to be mostly copper and coal, as I would expect. WIT reports 80 copper veins in that biome, although it doesn't report for coal at the moment.

This is the pic from a Roofed Forest:

and this is from a Taiga:

Both count as forests, but there's a ton more (twice as much ??) coal in the Roofed Forest, and coal is set to:
S:BiomeListType=FAVORS
S:Biomes <
FOREST
JUNGLE
>

I think a Roofed Forest is:
registerBiomeType(roofedForest, SPOOKY, DENSE, FOREST );

Using newest versions(FunOres-1.11.x-1.5.2-104 & SilentLib-1.10.2-2.0.3-43), no longer get crash with inventory, but same results for odd spawning as above in Roofed Forest & Taiga.

Also checked Plains, and this seems as specified (I think):

But Swampland is not even close, with lots of coal and iron, neither one of which is meant to favor swamp:

I used WIT in advanced mode, but it only seems to work on non-vanilla ores, so on coal, iron etc, it doesn't give the spawn info, and it looks like the vanilla ores are the main problem here.

Is it possible that maybe the normal vanilla ores are not all being removed ? Although that wouldn't explain the Plains.

Uploading 1.5.2b, let me know if there are still any issues.

It works ! Excellent work and thanks for all the effort.
