Minecart with Chest never gets cleared and instead refills when you close it, effectively duping the original loot infinitely.

EDIT:
Probably should have not been as hasty but busy playing ;P
Enigmatica 6 so Forge 36.0.10 and lootr-1.16.4-0.0.4.13.jar
Regular loot chests in vanilla villages worked fine.

The minecart also does not drop a chest when destroyed, and has no pick-block (pick-block of a vanilla minecart with chest gives a minecart)

a) Hm. This could be an oops on my part.

b) Hm, the first I can do something about, the second I'm not sure.

So, with Forge 35.1.7 and 0.0.4.13, I'm not able to replicate this in single player which may be why I've missed it. Going to experiment with server now. Disregard, I didn't test this properly as I misread the issue.

Yep, I am able to replicate this and I think I know the cause.

Yeah sorry I was playing on a server too, forgot to mention.

This is fixed as of 0.0.4.15.
