5.821 Changelog
Bugfixes
- Fixed a missing nullref guard from the galaxy map display mode for net metal, which could cause exceptions to happen in certain circumstances.
- Added a lower-bounds fix for Lists that prevents problems when the lower bounds are adjusted by multiple threads at once. Also adjusted our "OverLinkedList" so that "Contains" is now a pure-read operation and does not remove stale entries, since that was causing some cross-threading issues.
- Fixed yet another issues with the multiplayer sync logic after force-resync. Essentially, during this process, the host was still sending too much information to the clients, and that was causing the client to get stuck behind the host. This basically was a recover-spiral, but it should no longer have that issue.
- Fixed an issue where if there was a mismatch in existing savegames between what kind of faction the game thinks it was supposed to be, and what kind of faction external data was attached to it, it will automatically fix that rather than erroring. Thanks Oli for reporting.
- Fix some intel menu related bugs
Forge of Empires
- Intel menu improvements for many of the new player factions
