Well ok, thats why I quited play.

It was not possible to build large train-network because of that the train will collide with large bug, get stuck, and be destroyed. The game ended in going around and do manual maintenance on train network.

Continue play after a paus in playing.

The bug is not corrected.

I don't consider this a bug. If you built rails right through biter territory would you expect them to just ignore everything happening that you did? Now the same applies for building rails and then the biters migrating around instead of a magical "oh we can't build bases here because there's ...

No is not fixed...

I having about the same problem. I play my games in Marathon mode. That means that everything is extremely expensive and it takes lot of resources to evolve the factory. The pictures is showing my current game. One main base 15 self sustained Exp with automated replacement of spare-towers, ammo and ...

Yes it is!

Saw that you are not sure if that is a bug or not. I think it is a strange behaviour but it is not a big thing. Does not affect game-play-experience.

I do think that the intention was good. But in this case it have cripple the meaning to build rail then you have to protect it with walls and towers. A base. In my case probably several thousand of them and it will still not help because of that the bug nest spawn to close to the tower, but just out...

Add a example:

The picture show a new bug nest that have been created by/on the rail just after I kill the one before.

In a wast rail-network its begin to be boring to always have to follow the rail back and forth to change locomotive clean out bug nest that have been created over the rail.

Well, the inserter before/after the underground belt cant find any place on the belt for more Iron Ore but by the entrance/exit of the underground belt there is suddenly place on the belt.

Inserter finds place on full belt then entering underground belt. Se picture

It's a bug. In my current game I have about 14 expansions (marathon) and half of my time goes to clean out bug nest that building over my rails and placing new locomotives for those that have been destroyed. It is not possible to automate that. In my point of view the insect should not want to build...
