I have it set to false but it keeps on taking out maps of the votes based on what it is in the "recentmaps.txt" file. I thought setting "MapsBeforeRevote" to 0 would fix this, but it just causes the maps to never be put back into the vote (I assume because it counts starting at 1 and not 0). The best I was able to do was set "MapsBeforeRevote" to 1, which causes all maps to be available except for the previous map that was played.

Edit 1: It seems like it was solved on their github version in 2014. https://github.com/tyrantelf/gmod-mapvote/tree/master/lua/mapvote. I will see if I can download that version.

Edit2: I removed the workshop from my server collection, so the server doesn't download the addon, but left it as a resource so the client could download the addon. I then downloaded the github version and put it on the server. This fixed the issue. Please update this version to the latest github version.
