Hi,

I'm playing on a multicraft server with a friend. The server has FTB Revelation 2.5.0 running (updated) since yesterday.

In the basement of my base, I have a little XP farm running. After liquid XP piling up without being able to store it, I found a way to store a lot. I take the liquid XP from the tank, solidify it with the Experience Solidifier and let the Experience Solidifier transport the Solidified Experience to a YABBA Barrel through an EnderIO item conduit. Also, the Solidified Experience as mob drops also get transported to the Barrel. The system worked great, I recently passed 50k Solidified Experience.

As of just now, I wanted to gain some levels for enchanting. I took a few stacks out of the barrel and used them up. I then noticed I did not gain any levels. I then remembered I had a Tome of Knowledge in my inventory with auto-collect enabled. Not being sure whether the Tome gained any XP, I disabled the auto-collect and tried again, but I still gained no levels. I wasn't carrying any mending enchantments or other XP-using items. I went upstairs to get some Solidified Experience I remember getting from mob drops. I used them and they worked. I took the working Solidified Experience downstairs and mixed a bugged stack with a working stack. After this, none of the Solidified Experience worked. I also tried taking out Solidified Experience directly out of the Experience Solidifier and they did not work.

So, the Experience Solidifier seems to be creating unusable Solidified Experience. I hope I've been clear enough in order to be able to create a solution for this. If you have any questions I'll try to answer them. If you need any versions please explain where I can find which versions I'm using.

Were you still standing next to the solidifier? It'll pick up the orbs spawned by the solidifed xp, which would make it seem like it's not doing anything. It's a design flaw, and I'll probably make it directly increment XP or something, but for now, just don't stand next to it.

Oof, I think you may be right. I'm going to check if it works out of range of the solidifier. I feel like I should've thought of that though, haha!

You wouldn't happen to have the Clumps mod installed, would you?

The complete FTB Revelation 2.5.0 Pack. I checked and (unfortunately?) yes, it's installed: https://i.imgur.com/lWT1jXI.png. I assume this is causing the issue?

Edit: I completely confused this comment with another issue I addressed haha. But yes, it's installed. And I also tried the solidified experience out of range: You were right, it works out of range.

Yeah, we mark xp generated from the solidifed XP with a tag so the solidifier doesn't pick it up, but when clumps merges orbs, the tag is voided.

Default behavior is now to only spawn orbs if its detected a FakePlayer is using the item. Otherwise, the player xp will be incremented directly.
There's also a config to make orbs always spawn, if anyone wanted that.
