[0.18.8] Biters stop attacking

[darklich14]

Biters won't path through wide landmasses to retaliate against an arty train. Here are screenshots and a link to the save file.

Thanks for the report. I took a look at the save and when I shot at the biters they did come and attack. I think you just aggroed so many at once that it just takes time for the path finder to work out where to send what. The path finder is artificially limited otherwise in these kinds of situations you would run at single-digit UPS while it ran.

I'm not necessarily convinced that "they just take time".

Looking at viewtopic.php?f=7&t=81238 I continued the savegame just fine. "Mine" definitely should be or have been aggroed as they gathered as result of their nest being destroyed by artillery. Yet another 100 hours futher into the game, they did not make any progress and still remain there.
