The server crashes when the player relogs referring to 3d_armor (again?)

[Timofei302]

I'm building a Minetest server to play with friends. And while testing the administrative part of the server and the Troll mod, I ran into the problem that when reconnecting the player, the server crashes with a lua error. And judging by the error, this is caused by the 3d_armor (and skinsdb) mod.

this is a bug in a mod that's registering a callback w/ 3d armor, not 3d armor itself. we can't see what it is, because the path to the mod's code is replaced with (load)? can you provide a list of other mods that you have installed?

[fluxionary]

the code in question belongs to i3, which doesn't generate sane stack traces because it isn't written in lua. i suggest you switch from i3 to unified_inventory.

Yes. I have I3 installed. When I sit down at the computer, I will check whether replacing I3 with

And I finally tested the fluxionary assumption. Yes, the problem turned out to be in the i3 modification. Therefore, I think it's worth closing this issue.
