Yeah, Unfortunately I Made a really stupid mistake and forgot to check if the effect was disabled, Which I've Fixed in 0.29.1 so unfortunately the only solution is to enable the effect again, or to update Trinkes and Baubles.

ok the crash only occurs in combination with enhancedVisuals Mod if the slender-handler is disabled manually (had to do it for a mob farm), so this issue may be closed
