The map Jondome came up 2 times in the mapvote last night while I was playing on the Modded server.
The problem is that the preview image for Jondome showed up as a missing texture on the map vote screen (see below) both times it came up for a vote.
Steps to recreate:
1. Finish round 6 of a map that is not Jondome.
2. Have Jondome come up as a selection in the map vote window.
Proof of bug:
Hopefully this can be fixed soon.
