Stockpile barrels crash the game when Hopperhock flowers are used to add the specified barrel item to its inventory whenever there are more items to pick up than the barrel has capacity for when it's not completely full.

I was unable to replicate this bug using vanilla chests under similar conditions.

Thanks for what is otherwise a really nice storage mod, btw. :D

Thanks for reporting. Might be a few things since barrels' inventory implementation is a bit hacky -- could you attach a crash log?

Our server is being hosted on a hosting service, and the person running it wasn't comfortable with crashing the server for a log. So I copied the instance of our mod pack, ran a local server, and replicated the issue. Here is the crash log.

Thanks for taking the time to look into this.
