My friend sent me a version of StackSizeController, stating that it works in version 1381, but in the console it is written an error ( prntscr.com/nwgtxn ) I have already tried using the latest version but it does not work. I would like to know if anyone has the version of this plugin that works on v1381 (Devblog 116).

Sorry, we do not support older versions of games. I'd suggest updating to the latest and official versions.
