server crashes when trying to break a slabby block (dunno what else to call it) about full-slabs

[Micalobia]

Could you give a crash report, and/or a list of mods? I don't have any issues breaking slabs on either client or server last time I checked, although I can certainly check

[Neeko-iko]

yes sir
what i find most strange is that it crashes just the server, the client seems to process it fine

generally we try to run the server with not clientside mods, but for this example i wanted to make sure they were both the same- as i said before.

thank you for your help, btw.
