1.17.02.52 Plugin loading/missing bug

[LPChip]

Full Version:
OpenMPT v1.17.02.52

Has the bug occured in previous versions? If yes, please specify version(s): (This option is optional, and doesn't need research. But in case you know...)
Haven't tested

Description of the bug:
If you load in a song that uses a plugin that you currently don't have, it gets added to the list of plugins installed. I don't get a message that asks me if I want to search for it on KVR. Possibly its still in my cache somehow, but I don't use the plugin anymore, so I removed it.

Now, I have closed OpenMPT and reopened, and I get the message that it can't find this plugin, because it was added to the list while the file doesn't exist.

How often does it happen?:
Always

How to reproduce (step by step description):
I guess this has something to do with adding a plugin.
Make a song with the plugin, then move the file itself, then removing it from the list, then load a song that uses that plugin, then close mpt, then reopen.

Fixed. Deleted plugin files that were previously cached but are no longer in the list of known plugins should no longer get re-added to the list automatically.
