Hello,
We developed and launched Zombie Season late last year and haven’t made any changes or updates to the experience since. We only recently realized the AI pathfinding system has completely stopped working and our Zombie either sand still or just hop in the wrong direction. The intended behavior is they spawn into the level at various destinations and all move towards the central building the players have to protect.
We believe this to be a Roblox studio or feature update because we are not getting any errors in our console.
We read on the forum this could be breaking due to smooth terrain and could have been triggered by a Roblox update.
Thanks for reporting this. We did make an update to pathfinding early April this year. Do you know when did this start happening. This is the first report regarding Pathfinding completely not working since the update, so unfortunately I dont have a quick fix. We will investigate and get back to you.
Closing the loop on the original issue for future visibility - We recently improved pathfinding behavior when some parts are very far in height/depth and return Failure for the requests to avoid OOM crashes. In this case, we worked with the developer to adjust the distance of the parts, which was sufficient to avoid this early-out behavior while still meeting creative intent.
Pathfinding is still very broken. We have issue where pathfinding modifiers(Radius and height) dont always take account, and pathfinding gets stuck on wall corners a lot
