Additional Information and Notes
No response
Game connection crashes at ItemRepository.cs at line 73 when the swap is called
await _cacheManager.Set(key, item);
The previous write to the database, line 70, goes through and it is persistent between restarting after a crash
So the problem is likely in / with Redis and or caching.
I'll take a look for the Redis part. But my strongest guess is server-client packet order for equip-unequip actions
The packet handeling was my first guess, but it ended on line 73 and i have almost no experience with memory so i thought its probably wrong. But it still needed a restart of the server to be able to rejoin the game since it stated that the user was already connected, so server-sided it may have stopped registering new packets because of a faulty predecessor.
You don't need to restart the server after getting the "you already logged in" message; just try logging in again, and it will succeed. That's another bug related to the unexpected drop of connection. I haven't had a chance to take a deep look yet, but packet order is still my strongest candidate for this issue's root cause.
I also discovered a significant number of bugs with item and inventory management. I’ll open respective issues for those as soon as possible.
