Hey Vazkii,
not sure if this is a bug with botania but I'm using a personal modpack with just botania, tinkers construct, baubles and a few chicken bones mods (nei, ender storage, and core). The pack is mainly to experiment with botania fully as it is one of my favourite mods. The bug I'm getting is whenever i open a beacons gui and hover over one of the highlighted buttons (to select the effect) i crash. The game closes without going to the crash screen and saves a crash report. Just having the beacon gui open is fine but when i hover over the buttons then i crash. Due to the lack of a large amount of mods in this pack I am assuming that the issue may be with botania (I dont think tinkers modifies the beacon). Also I noticed a semi new gui on the beacon that I believe comes from your artistic genius, it may be a vanilla update but I'm not sure. Also i should clarify that the modpack uses minecraft 1.7.10 and the latest version of botania at all times and the modpack is created using multimc (also latest version).

p.s. Keep up the incredible work with botania, the mod is amazing and I can't wait for future updates!

Thanks so much!

Thanks a lot!
Ill test that right away and post the results in a sec.

Botania has nothing to do with this, you need to update NEI.

Yeah thanks so much!
Yeah i was running the recommended version of the chicken bones mods which were very out of date. Now running the latest versions and everything is working fine. Im going to go fight the gaia boss now, wish me luck!
