Failed compiling 'PlayerAdministration.cs':
1. 'BasePlayer' does not contain a definition for 'lastAdminCheatTime' and no accessible extension method 'lastAdminCheatTime' accepting a first argument of type 'BasePlayer' could be found (are you missing a using directive or an assembly reference?) [CS1061]
(PlayerAdministration 25 line 1292)

You can comment out that part if you don't need that functionality.

I posted a fix under uMod - Error compiling after today's update - Player Administration - Community
