I've noticed that I keep seeing Expert and Nightmare bases being spawned. The problem is I didn't add any bases to the profiles for it to choose.  It seems to be choosing random bases from copy/paste.  I've since put a -1 after the expert and nightmare amount to be spawned and hope that does the trick but I did want to report this issue regardless.

it can't spawn a base that isn't in a profile 

I assure you that's what was happening.  I kept getting Expert and Nightmare icons on the map and random bases that I use for medium/hard.  I checked the profile for expert/nightmare to make sure none of my bases were listed in there somehow and they are not. 

post the profiles and the names of the files it spawned

also no idea what you're implying in regards to random bases for medium and hard

I'm saying that even though I haven't defined any bases for expert/nightmare it's doing it anyway and using copy/paste files that are medium and hard bases.  I'm not sure it's still doing it today I've been busy and might have missed it.

ok, now I just caught it doing something else wrong.  It just spawned a copy of a base I recently copied as mediummellonpopr1 and I did NOT add to the medium profile.  I wonder if I have some old files left behind from the previous incarnation of the plugin.

I double checked the medium profile, that base (mediummellonpopr1) is not listed anywhere in there.

I just don't understand how this is happening because it should not be possible. It must be another plugin causing this to happen... so I will add another check to prevent that specific case from happening

Yeah it's strange, I wonder if I have remments of the old version causing problems.  What files do I keep beyond the "Profiles" folder and the .cs file itself?

zip your config for raidablebases, and any backup configs it made. include oxide/data/RaidableBases as well

upload to dropbox.com and send me the link via DM. i will respond here instead of DM

hey Nivex I just wanted to let you know that I ended up deleting everything I could find that was related to the plugin.  I then tested some bases with copy/paste and found a few easy level ones that apparently became corrupt at some point.  I replaced those with new bases and tested the rest of them in each category.  I then re-installed the plugin and configured it.  It's been running for several days now and I'm starting to see a worlds better mix of bases, many that didn't spawn previously and I'm no longer seeing Expert or Nightmare events.  I THINK it's working properly now but I'll continue to monitor.  I appreciate you taking the time to look into this.
