The research table were working fine till Direwolf 1.0.4, not sure if any of the mod changes could be causing the issue or maybe if they messed with some of the configs.
Edit 1: Tried using a downgraded version of Direwolf 1.0.3 and the table still broke, maybe is the new launcher version that have some kind of issue?
Edit 2: Tried using Default textures and the table were fine but as soon as i loaded the resource pack for the first time both Default and Soartex versions broke. Resetting the client using Default textures fix the table GUI on the vanilla ones.
Edit 3: Tried using a Hand made soartex from files taken out from the master file that i had from 4 days ago from the Git Hub, and the table worked just fine.
Edit 4: Seems i found the solution, your "guiresearchtable.png" is broken, i replaced with my version from Git Hub master files and now it works fine. I uploaded the version that is working for those that want to fix it.
