My Schematic had some enderchest in it, when building it Schematicannon, server crashes, it gets in a crash loop as after starting server it tries to put it again ....

Modpack is valhesia 3. Details in crashlog here: https://pastebin.com/2pVRgx2i

This issue (null pointer exceptions being caused by LivingEntity being null when blocks are placed by Schematicannon) has since been fixed in both Ender Storage and Storage Drawers.

it's has nothing wrong with enderchest, just ban it plz!!!

to save your server, delete the schematic folder on your server side. i managed to save my server through this way

i found the cannon will randomly cause crash on server side. it has a high rate to occur, it's a well-known bug and haven't been fixed.

I found that this also applies to Storage Drawers
