Speaking of this MapChooser, it's time to release a new version. Here's what's new in 1.5.4:
- Ported the SourceMod 1.5.3 double-nomination bugfix to NativeVotes MapChooser.
- Ported the removal of g_NominateCount from SourceMod 1.5.3, should fix nomination count being off.
- Better detection of SourceMod's MapChooser, since this can't run at the same time as it.
- No longer tries using NativeVotes votes on games that don't support multiple choice votes (although why are you using this MapChooser on a non-supported game?)
Note: Although this is compiled against the NativeVotes 1.0.0 beta 3 nativevotes.inc, it doesn't use any 1.0.x features and should work fine using NativeVotes 0.8.x.
Edit: Sorry, spotted a last minute bug I needed to fix. New version is posted now which fixes it.
