I've not see this, but I think I know what's going on. BasicChest and TreasureChest have a line that makes sure the loot is being put in a chest. Its very unlikely this would ever happen, but a few blocks are protected so the mod can't replace them (spawners, chests, and the end portal get this). So its possible that it just lucked into trying to replace a spawner with a weak chest, and then crashed because there was no chest there. Thanks for telling me. This is in all versions, but an easy fix (I think I just fixed it in the 1.11.2 version after reading this). It may just be a little bit to port the fix to other versions and get everything updated online.

[BlackJar72]

OK, try the new version 1.9.2 -- it's should be fixed now, if its what I think it was. (It would be helpful if you test with the same seed since this seems to be a rare crash.)

If not, I'd like to know if you're using the default themes or have made changes -- my next guess would be a problem in chests.cfg.

[LemADEC]

We're using the default configuration for the mod. I've no idea on the coordinates where it happened in the map.

[BlackJar72]

Have you tried the new version at least?

[LemADEC]

it'll be in our next update of the pack, probably this week end, thanks :)
