+Subject: [PATCH] Do not run close logic for inventories on chunk unload
+
+Still call the event and change the active container though. We
+want to avoid close logic because it's possible to load the
+chunk through it. This should also be OK from a leak prevention/
+state desync POV because the TE is getting unloaded anyways.
