Thanks! It's fixed and now throughput is consistent across all cases, even corner belts

This is adjacent to [https://forums.factorio.com/134061], which was marked as "not a bug" which makes sense (left relative lane preference is (was) a feature), but in 2.1.7 the inserter logic changed, which was undocumented in the changelog (or it's accidental and came from some another unrelated ...

man, now parallel belts direction also affects throughput because of the rotation preference changes!! in 2.0.73 (I will test it at 2.0.77 a little later), they are fully symmetrical, throughput is practically the same (not sure why it differs by 3 items, maybe some rounding error, doesn't matter ...

at stack size 12 bulk inserters, throughput is now higher at west inserter only by one stack (1320 vs 1272 in favor of the east one, ~3.6% higher) instead of like 25% in the first post, although still it's weird that the west inserter now inserts clockwise and returns counterclockwise which is ...

and instead the east one now rotates all the way counter clockwise instead of making a half turn clockwise like the west does and the east did in the eugenekay's gif above but taking from the relative left lane?? lol

I guess it has something to do with which lane the inserter prioritizes.

Yes, from the Wiki again:
If the belt is the same/opposite orientation of the inserter or a curve, the inserter prefers taking from the left lane, from the belt's perspective.

- What did you do?
I was testing inserter throughput when I stumbled upon weird behaviour when taking from corner belts going into an inserter.

- What happened?
Left to right belt going into an inserter has higher throughput than right to left belt in the same exact setup.

- What did you expect to ...

+1, also temporary drawings (like in Valve's Deadlock) that disappear after some time would be lovely.

TL;DR
Make big power poles' circuit wire reach equal to it's power wire reach for all entities

What?
For red and green wires, currently big power poles can reach each other easily, but for other connections it's the standard reach of 8 (9 because it's a 2x2 building) tiles as with all other ...

Thank you, i didn't know about new update. Sorry!

After some hours into the game close to my base (i think) spawned some biter nests. And they started attacking, but every time an army of them (20+: lvl1,2 biters, spitters, prolly) attacks me, or my base, and if i see them, the game crashes. As is said, it crashes only if there's so much of them ...
