Playing as a dragon prevents the Chisel mod's chisel GUI from opening with right-click. This occurs as any dragon type, and only on multiplayer servers. The GUI appears normally on singleplayer worlds. Other items with GUIs (ex. Ender Pouch from EnderStorage or Engineer's Manual from Immersive Engineering) function normally.

Forge version: 36.2.0
Dragon Survival version: 0.0.43
Chisel version: 2.0.1-alpha.4

If this issue is not caused by Dragon Survival I'll take it up with Chisel instead.
