Frozen biters fixed in Factorio 17.74 stable?

[PabloP384]

Hello, how are you? I am from Argentina, I would like to know if the Frozen biters bug has been fixed, there comes a time when enemies pile up causing a lot of lag and do nothing
I would not like to think that it is because of some mod installed because I don't know which one it can be
Thanks in advance

There have been several pathfinding changes in 0.17 that could have changed how often biters freeze, generally biters freezing can be intended for performance reasons, so if your issue does no longer occur no one can tell you unless you post a save file.

Some more information on the pathfinding can be found in this FFF:

After these changes were implemented, some additional bugfixes had to be made. Chances are high that the problem you describe was fixed in that process.
