I just experienced a new kind of client crash. Maybe its an old style FRE but with new popup due to new C++ update?

I was trading items (tech parts) between 2 of my characters when one of the clients died with the following error message:

Runtime Error!

Program: F:\spil\neocron2\client.exe

R6025
- Pure Virtual Function Call

Happened around 20.55 in Praetorians starter appartment. Client had only been running a minute or two upon crash.
Characters: Praetorian (client crash) and Green Researcher (did not crash, techs returned to inventory upon other clients crash)
