Can it be reproduced with just Tinkers Construct? If not, list the other mods required to reproduce the issue.
No, ive isolated TC and i even tried adding mods one by one, but i can't even recreate this effect on a singleplayer world with all the mods that this error originally occured with.

this issue was fixed after a server restart; filing here for documentation purposes
