[TelepathicGrunt]

Jei resources may be passing a null entity to the trade system which crashes. They will likely need to adjust their code. See if there is a report already on JER repo

[TelepathicGrunt]

yeah I don't think this is an RS issue. More likely to be JER https://github.com/TelepathicGrunt/RepurposedStructures/blob/8f8e9a7a456389530520235fb956fa02a32e1595/common/src/main/java/com/telepathicgrunt/repurposedstructures/misc/maptrades/StructureSpecificMaps.java#L53
