The AoC for Cazic Thule is missing the An Acidic Mass raid encounter. It only spawns in open world. I believe it should be in the AoC because the OW version does have MOTM IV on it, indicating a raid level encounter (and it certainly has the hit points of a raid encounter). Either it should be in the AoC or MOTM should be removed from it. Additionally, given that the Cazic Thule AoC for the upgrade version of the zone doesn't launch until PoP it makes sense that the MOTM level for this zone should be 5, not 4. I should note that it seems the AoC is missing a LOT of spawns. I don't know if this was an attempt to prevent any named from spawning (as I've never seen a named spawn in the AoC), but perhaps this is why an acidic mass is not showing up.
