Alright, I'm back from my break and I'm working on this map again, and I'll (hopefully) be able to have my newest version of this map tested. If anyone can point me in the direction of who may be able to host it, I'd be thankful. (And testing it as not a full version but an in-development version).
You can have it tested right here on the TF2Maps servers! You have a choice of either submitting it to the Saturday gamedays (rules here, submission opens Thurs/Fri) or hanging out in the steam group chat and putting your map forward when an impromptu test is being organized.
