I'm not sure why this is happening. My guess is that it is happening to lots of people on quite a few servers judging from forum posts. I cannot see my server when running the game through EPIC.
NA-PVE-Official-CrystalIsles853
I'm playing via EPIC, and this server does not appear in the server list, and many other servers are not showing up also, like most of the NA-PVE-Official-CrystalIsles85* servers are not there. 853 shows up in my Favorites list, but running it from there crashes the game to desktop, with an unhandled assertion:
Assertion failed: IsValid() [File:F:\build\SummerBash2021\Engine\Source\Runtime\Core\Public\Templates\SharedPointer.h] [Line: 658]
which is the shooter_game!opus_repacketizer_out_range unhandled exception.
This is obviously a significant issue affecting many people. I'm surprised Wildcard has not really said anything about it and is just leaving us to stew in anger. That's just a bit careless.
