Multiplayer Connection Drops and Black Screen Bugs in Core Runs

Steps to Reproduce

  1. Start a multiplayer Core Run with friends as a client (joining a friend's lobby).
  2. Play through the run until reaching Depth 4 (out of 6 levels, Hazard 2, modified complex).
  3. Experience a sudden network disconnection from the host/lobby.
  4. Attempt to reconnect to the same friend's lobby for the first time (rejoin fails/disconnects again).
  5. Attempt to reconnect for the second time.
  6. The game fails to load the level and gets stuck on a permanent black screen instead of spawning into the game.

Explanation

Dear Rogue Core Developer Team,
I am writing to express my deep frustration regarding the multiplayer connection issues. I understand that the game is in Early Access and still very new, but the frequent problems when trying to join friends' lobbies are making the experience incredibly painful.
I just got disconnected from a game twice in a row and was completely unable to rejoin. What hurts the most is the lost progress. My friends and I were on Depth 4 of a 6-level run, playing on Hazard 2 with a modified complex. After investing so much time into this specific Core Run, getting kicked out was disheartening enough. But when I tried to reconnect for the second time, I was just stuck on a permanent black screen.
It is deeply frustrating to lose a great run and all that momentum to technical instability rather than a tough fight.
I truly hope you prioritize fixing these lobby connection drops and the black screen loading bugs in the upcoming patches. Right now, the multiplayer is borderline unplayable for me.
