[Oxyd] [1.1.6] Biter groups for nest building waiting on stuck members

[LiquidInsight]

Hi all,

I've followed the recent bug reports on biters failing to attack with great attention, because my current multiplayer server has been suffering from larger groups of biters forming up on the southern edge of our base, and then failing to do much of anything. I saw two such bugs get fixed before 1.1.5, but it seems the problem still exists in the latest version of Factorio.

Problem description:
Biters form large groups of roiling bugs. It occurs most often to the south of my base on Nauvis. I've seen up to five or six group at a time, typically before I kill them with artillery. The save file has one such group right now.

Here's the offending save file:

and the log file is attached.

Thank you so much for you all your work on this game -- me and my family have spent hundreds of hours in this game.

The biter group is waiting for its pal to arrive, but his pal can't arrive because one of the mods means he can't kill the rock:

Not sure to call it a bug or a mod issue, will leave that for Oxyd to decide

I would prefer unit groups not to wait indefinitely as well. LiquidInsight, the link to the save has expired, can you reupload it?

[LiquidInsight]

No problem, I'm happy to hear this report was useful, here's the new link. It'll expire in a week I'm afraid, but I can re-upload again if need be

No worries, I got it in time. I added a timeout, so this shouldn't happen anymore in 1.1.9.

Exciting! Thanks Oxyd.
