Unknown incompatibility leads to changing piston state crashing the game

[SiverDX]

1.19.2 - 0.2.8

I'm assuming this does not happen on a not-so-modded client If the pistons are already in a activated state it's fine - but changing the state (to either extended or unextended) crashes the game

I did also find this: https://www.reddit.com/r/fabricmc/comments/12vuziu/game_crashes_when_piston_is_activated_due_to/

Deactivating Canary stops the crash from happening

After loading into the world:

Tried alloc.enum_values.piston_block=false in canary.properties, did not work: [01Aug2023 02:19:21.199] [main/WARN] [CanaryConfig/]: No configuration key exists with name 'alloc.enum_values.piston_block', ignoring

[SiverDX]

Manually removing the entry block.moving_block_shapes.PistonMovingBlockEntityMixin works

Regarding the config - is the syntax I used wrong? block.moving_block_shapes.PistonMovingBlockEntityMixin=false seems to not be correct

[SiverDX]

okay, mixin.block.moving_block_shapes was the correct one
