Tropical Island map not completing.

I ran a Tier 8 Tropical Island as a rare and killed the boss. The map did not complete. My bug report number is 308,629,025. Are there multiple T8 Tropical island maps from previous expansions or something that do not count on the Atlas?

Most legcy maps have different tiers than the current ones, so you don't get the same completions. It gives you an equivalent tier completion to the map you ran.

This map was the correct tier (8) and had the right art work.
