I also have an issue with the bot warfare mod as of today. I believe an update from today (May 4th 2024 US) may have changed the bots' behavior. This happens when I'm deploying bots in private match. I played with the same settings yesterday and the bots were working fine.
Here's a short video link that's similar to what Claux is describing: https://www.youtube.com/watch?v=XPvxp7QR0Jk
At 27 seconds into the video, the enemy bot I'm facing doesn't seem to move at all even when I am at his face. The difficulty setting was set as very hard, but this same issue occurs for lower difficulties like easy-med, etc.
