I just got peer confirmed that whenever a PACKAGED Lyra 5.4.3/5.4.4 Dedicated Server performs a map Reload or map Change WITH one or more clients CONNECTED, it will 100% of the time CRASH.
This ONLY happens for PACKAGED builds and ONLY if Clients are connected to the dedicated server.
In PIE Mode this scenario DOES NOT crash the dedicated server.
A first quick analysis seems to point to the issue being caused by trying to “sync deleted actors”.
This crash was reliably replicated for packaged dedicated servers for Lyra versions 5.4.3 and 5.4.4 by peer reviewers.
