I am trying to make a Deathrun map, which according to the plugin page on AlliedModders (Link), requires tf_logic_arena I've been working on my map and beta versions have been up on our groups server for community testing, running absolutely fine. I had build the map following this guide. The map ran properly in Arena mode when compiled and on the server. However when now when I try updating the map to fix the issues found in testing, it does not run in arena mode. I did NOT edit any of the game rule entities. I only adjusted brushes and clipping, and settings of other entities. I even compared the last working version with the version I am working on, making sure the entities are set the same. I have tried compiling the newer version with the settings exactly the same, and with them set differently. The only thing I have not done is try recompile the older version to see if it runs in arena mode, which I will probably do next. In the mean time, does anyone know what might have caused this?
