FAQ - Steell/Ultimate-Mapchooser GitHub Wiki
###Why are my nominated maps not appearing in votes? The most likely culprit is that the map you're nominating has a different group name than a group that's actually in the vote. This commonly happens when you have separate groups for voting/nominating, and it happens more often when there are separate UMC-Mapcycles for voting/nominating.
To fix this, you can specify which group a nomination should belong to by using the nominate_group option, outlined in the documentation for the Core Module. This way you can set which group nominated maps belong to without altering the structure of your nomination groups/mapcycle.
###Why is only one map/only nominated maps appearing in the vote You probably forgot to set maps_invote in your UMC Mapcycle definition. This option specifies how many maps from a Map Group to be included in a vote. If it is not set, it defaults to 1.
###How do you use Ultimate Mapchooser in conjunction with GunGame There are several versions of GunGame around. The one recommended for use with UMC is the SourceMod variant, which you can download here. To use UMC with SM GunGame, first make sure the Vote Command module is enabled and configured. Then, add the sm_umc_mapvote command (with appropriate arguments for how you want the vote to run) to the gungame.mapvote.cfg GunGame configuration file, located in the cfg/gungame directory.
###In TF2, why doesn't UMC change the map for me when the time remaining reaches zero Valve has this functionality built into the Source Engine. If you set the console variable mp_match_end_at_timelimit to 1, then all maps will end the second the time remaining reaches zero. This console variable defaults to 0.
