Bahlak, The Sky Seer goes invisible after 1m tornado (video)

Bahlak, The Sky Seer, encountered on the map Cenotes seems to have multiple issues:

1. He sometimes goes invisible after his tornado phase.
2. He seems to have random periods of invulnerability.
3. His tornado can last a long time (one recorded at 57s long) and he stays in it the whole time so you can't approach. Also he keeps doing is normal moves and can teleport bringing the tornado with him instantly with no warning. It seems like he is acting as if the tornado phase should be over but it is still going erroneously.

I know, skill issue, i should play a build that can kill him before he gets to the tornado, but it would be nice if these issues were fixed anyway.

Here is a video of one of my fights against him: https://youtu.be/UkLIGJMcV1A

The 57s tornado starts at 0:47 and ends at 1:44 when he goes invisible until he kills me with the next tornado.

I have encountered the same issue on the same map.

When bahlak starts the big tornado it never stops, he is involnerable while in it and can continue as if not in it and do his normal attacks.

The boss in uncompletable and i must skip this map-node.

I've seen this too. I logged out but he was still stuck in the tornado. It took about a minute for him to stop.

Had this happen as well.

Yes, this has happened multiple times to me on the Cenotes map. He makes the tornado and then gets stuck inside it. He can be hit sometimes with aoe attacks, but when he does the teleport attack, he transports the tornado on top of you and kills you. The tornado does not seem to stop, or at least I haven't lived long enough to see it stop.

REALLY annoyed because this was a corrupted nexus and he wiped me.
