BUG: Soft-whitelisted mods are ignored after the first connection #19

Closed ascenkka closed 7 months ago

ascenkka commented 8 months ago

Describe the bug Client disconnects after reconnect due to an invalid hashsum, although all mods match the configuration. It seems that anticheat stops taking into account mods installed on the client, starting from the first connection. Two specific mods with hashes 1b31217564427ce561c6ca77fdfa3466 (Litematica) and 5db8fbcf75e3eb2b81e67aed577ab579 (Malilib), which were installed on the client, are in the whitelist at the first connection, but missing at the second (hence are included in combined hash). first-connection.txt second-connection.txt

To Reproduce Steps to reproduce the problem:

  1. Launch the game with optional mods
  2. Connect to server
  3. Disconnect
  4. Connect to server once again
  5. Disconnection due to failed modlist check

Expected behavior Allowed connection with soft-whitelisted mods

Sorry for taking so long to notice, the issue should be fixed. Will be pushing a new release momentarily.
