I was trying to start my altered version of the modpack direwolf20 with the following crashlog from MultiMC: https://paste.ee/p/lgaRu
, these were the mods that I added to: FTBPresentsDirewolf20112-2.1.0-1.12.2
TinkerToolLeveling-1.12.2-1.0.5.jar
SoulShardsRespawn-1.12.2-1.0.5-7.jar
sonarcore-1.12.2-5.0.14-12.jar
RandomThings-MC1.12.2-4.1.9.jar
Quark-r1.4-125.jar
OreExcavation-1.4.119.jar
NaturesCompass-1.12.2-1.5.1.jar
fluxnetworks-1.12.2-3.0.15-9.jar
EnchantmentDescriptions-1.12.2-1.1.6.jar
Ding-1.12.1-1.0.1.jar
Cyclic-1.12.2-1.16.2.jar
conarm-1.12.2-1.0.1.2.jar

Crash happened on boot up.

I tried using a fresh instance with just the mods
AutoRegLib-1.3-18.jar
Quark-r1.4-125.jar
no issues then, I did try as well with a previous version of both of those mods with the modpack above and that still showed the launch crash. As well as removing some of the mods that I know have a lot of block IDs in use.
From what I can read of the crashlog and my comprehension it's something about max ID range is being reached, but I do not know how to increase that or am I just using too many mods :(

Thanks for any response.

You ran out of block IDs. The best you can do is either remove mods, or use the config setting in the general part of the quark config to remove the mod's stairs and slabs.
