This crash only happens when injecting potions into tubes?
If so, would you mind posting a link to the potions code, thanks.

It happend when tubes detect a throwed (for example by a witch) potion near of tubes

So by dropping items near sand-tubes or adjustabe sand-tubes I should be able to reproduce this?

I'm having trouble reproducing this.
Would you please drop a link to the mod that provides the witches.

I've tried with mineclonia and VoxelLibre (both from CDB) and in neither have I been able to make the game crash nor have the sand-tubes picked up any items.
