Hello there,
our Server crashed twice (5 min inbetween) after mining End Lapis Ore (from Cyclic). He used an Tinker Pickaxe (Cobalt Head/Cobalt Binding/Titan Handle/[following upgrades: Unbreakable, Luck 3, Excavate Level 25, Hastester]).
We guess its caused by Cyclic and the Excavate Modifier from OreExcavation Integration.

We don't have access to the files yet. If I get access to the crash log I will post it.

If you need anything else (I guess you do since I only have very less data) ask.

Version: allthemods 3 v.5.6
MC-Version: 1.12.2 (with mods) forge-14.23.1.2568

I will try to reproduce when I can but yes we very much do need the crash log to see what the root cause is and how to fix it (or which mod author to report it to)

We tested this with an identical setup on the ATM3 official server (also 5.6) including the exact tinker's pick parts and modifiers. We were able to excavate a vein of cyclic end lapis ore in the end multiple times and not encounter a crash.

That means without being able to reproduce on our end we can't do any more troubleshooting until we can see your relevant server crashlogs.

It's been a while with no response and we just released pack version 5.7

If you're still having issues on 5.7+ please open a new issue with crash logs (since we couldn't reproduce it on our server)
