1. Testing a battle inside of the Foundry results in incredibly easy mobs that almost instantly die. This makes combat preview unreliable.
2. Our away teams now disappear almost instantly. If #1 wasn't a problem, this NEW problem would make combat preview impossible.
3. Because of the new rewards system, we cannot test our maps post-publish unless testing takes longer than 20 mins. Otherwise, simply testing post-publish (because it's now impossible to test pre-publish) condemns our maps to not qualify for rewards.
There are many other bugs. Basically, we can't test play our missions. The preview mode has become: "Is that object where you meant to put it?" It's not useful for anything else.
