[PUDGE133]

fix bug/suggestion: discord topic

• Minor refactoring of commands
• Major refactoring of MapUtils.cs
• Minor changes in many files
• Update to the current version of Exiled

Test map. Don't forget to change the file extension to yml testmap.txt Test seed map_seed: 712170397. With this seed generation, there is no room RoomType.EzConference

If in my yml file, there are objects that are attached to non-existent rooms (for example, ezconference), then as a result, the previous code did not allow loading the entire map. Now the code skips objects that cannot be spawned in the game. The code compiles and runs on the server without errors. No issues were found during game tests.

the result of my work: test map main map
