Decided to kill a solipist, but kept resisting the damages, so I used the control skill on my thought form. got LUA error.

LUA error: /mod/class/Player.lua:353: attempt to call method 'updateMainShader' (a nil value)
At [C]:-1 updateMainShader

Got a similar bug once when I was controlling my thoughtform while the main character died. Inside the Eidolon, a similar LUA error would pop up. Didn't think further about it. Could be related to the special shader, that is attributed to the thoughform.
