Refers to UE-26025. Any updates on this?

Currently crashing on connected clients whenever I attach and then detach a replicated component on the authority.

Hey overlawled,

The current status of UE-26025 is that it is “in progress”, or being worked on. There is no information on when it’ll be fixed or what future engine release it will be in.

Is there any workaround for this crash? Currently preventing me from attaching anything that is being replicated as it causes all connecting clients to crash.

There is no work around posted internally.
