There seems to be some new bug related to switching between weapons on a MBT with the ones that should be ready to fire immediately such as cannister shells. Or maybe it's only cannister shells have not tried any others yet (besides Guided but that's got a targeting period). It's not needing to reload. This is a combo I use heavily on vanilla maps so I know something is different suddenly. In short, I switch to the damn thing and it won't fire for one or two seconds. Happens also if I am already on secondary weapon then switch to main gun. Really, really frustrating especially as it only seems to happen if an enemy is in my FOV (in other words, someone I want to fire at)! Can anyone else confirm/deny this? Don't think it affects the Destroyers such as with AP Shells and HE.
