I had reported this in-game a couple weeks ago and have noticed it was fixed temporarily but the glitch has resumed itself. Time Extension 3 near the gobbue mobs in Dynamis Valkurm has a habit of NOT respawning. While not everyone experiences this glitch, quite a few of us have, which then results in wasted dynamis visits for that 24 hour period being not able to get the last TE we would need. I watched a BST kill the TE which was invisible to me and my duo partner and another party in the zone. We could clearly see the BST fighting this invisible TE which could not be highlighted nor targeted by us. But the BST could see it perfectly. And the TE never respawned for us. Please look into this. Thank you.
