Technically not a bug report / suggestion i posted this in #questions and i feel like it would be better if i posted it here for the devs as well

Drill 1:

Drill 2:

Drill 3:

For drills 1 and 2 post server crash the glue detaches from my item vaults + mechanical drills
For drill 3 the drill just plain vanishes

When i was running my server it crashed once and all players was time-ed out (no crash reported created though) and when logging on my drills had issues ( Drill 1, 2,3) and when inspecting the issue server crashed again and generated a crash report (see bellow). Does any dev/fellow person know whats happening?

Server mod list:

My drills:

4 wasnt running at the time

Crash report:
message.txt

Contraptions have randomly disappeared on crashes for a while, but it's not really a priority since the crash usually is.

Is this still an issue? Haven't encountered this in quite a while. Closing for now.
