Summary of the problem Lootbag crash Pack Version 2.5.4 What is the bug? When someone kills a mob that drops a lootbag I get a crash. Same thing when I retry to login, and the lootbag is on the ground. It looks like it is client sided because friends who are playing with me don't have this problem. (Description: Rendering entity in world java.lang.ArrayIndexOutOfBoundsException Entity Name: item.name.lootbags_lootbag) Mod & Version I guess it is lootbags, for the entity what is causing the issue. That is version: LootBags-1.7.10-2.0.13. Link to log file http://pastebin.com/9gpEAJqW Is it repeatable? Only on my client currently, didn't see someone affected by it. Known Fix None other than let no lootbags drop the floor. And mob drops are kinda important.
