A really annoying bug is when you go on and then off duty a couble of times you have multiple running instances of plugins. Callouts can bug out cause multiple of the same is being called. Notepad when having multiple running also leaves multiple notes when only writing one. CompuLite when writing citations or arrest order, you see the same list go on and on depending on how many times you have gone on and off duty.
When running an plugin LSPDFR Enhanced that depends on going on and off duty this makes it a real problem. This is a big issue for every plugin.
Not to say it's a optimization issue as a whole.
