In the adv. search part of the teambuilder, when attempting to filter by stat, the =, >=, and <= do not show equal to, greater than or equal to, and less than or equal to respectively. Spoiler It looks like = has turned into greater than, while <= is equal.
I recall a conversation about this last night: You: Found a bug in the teambuilder where do I post it? Me: Solved Bugs (Its like I knew exactly what the bug was before you even posted!)
