1. Go to PLAY>MULTIPLAYER>BROWSE PUBLIC GAMES
2. Click on a server to highlight and view stats, wait for info to load in side pane
3. Repeat step 2 one or two more times
4. Change setting "has mods" to 'no'
5. Observe that the servers you've previously looked at disappear from the list, even if they didn't have mods

If you do the same process with servers that DO have mods, and select 'yes' for "has mods", then they will disappear wrongly as well. Servers do not disappear unless you've highlighted them first and then changed the viewing settings.

Please see my other bug report to possibly kill two birds with one stone:

Thanks for the report, fixed for 0.15.7
