Hmm fair enough, odd that they changed the 1.1 branch like that so they don't match:
sm version for example shows:
8:04 SourceMod Version Information:
SourceMod Version: 1.1.0-dev
SourcePawn Engine: SourcePawn 1.1, jit-x86 (build 1.1.0-dev)
SourcePawn API: v1 = 4, v2 = 2
Compiled on: Oct 19 2008 00:50
Build ID: 2370:43b134b35542-dev
Build ID is 2370 in this instance.
I will update the first post to reflect this and then I might try and upload a "compat" version or something which should run on the older release. If people want to try and use the move to spec option that might be another story I am not sure when the findteam function was implemented and people can manually add the semi-colon to the file as per https://bugs.alliedmods.net/show_bug.cgi?id=3376
if it does exist and you want to compile manually.
This plugin _Should_ work with any mod, that was my goal/idea anyway. Some mods won't be able to use the spectator feature due to not having a spectator team but for the ones that do I have tried to make that flexible/dynamic and not hard-coded to specific team ID's.
