AH really needs some code to allow maps with 2 sides. Almost every even is a 2-sided event, and yet we still have problems where you have to have a 3rd side's fields and HQ tucked away somewhere because AH won't run properly with just 2.
It's been 10 years, I figured it's about time this compatibility was coded in. MA and public arenas would still follow HTC's map submission policies (i.e. 3 sides, etc), but on the event a map with 2 sides was loaded, it would not create any issues. Meaning the policy dictates the map rather than the programming, if you get what I mean.
[edit: whoops, stupid laptop submitted while I was still typing. Fixed.]
