ProMods

It is because I and author of Promzona edited same sector on 2 different ways. Someone must merge them.

If I knew anything about the map editor I'd have a go at it but I've never even opened it and would probably just break something in the same way I managed to kill ALL my AI traffic a few months ago I'm not asking anyone actually to do it - though I'd be grateful is someone did - just offering a workaround.

Realistic Russian highways and Improved sempaphore cycles are updated. Promods version is ready again.
Please, do not discuss about Improved sempaphore cycles here.

brainiac, I have problem with your Realistic Russian Highways... I place it above promods def and game crashes. Maybe it's because of Poland Rebuild 2.0? I place it below Poland Rebuild and above, in both situations game crashes again. What could be the problem?

I didn't test with it. I even don't use Poland Rebuilding. With Southern region and Kazakhstan game don't crash. But I found critical bug...
If you want to find problem and how to solve, (baci pogled) look to game.log and read errors on bottom of file.

somac333 mine also crashed when i put it above promods def and i'm not using PR. Place Realistic Russian Highways bellow promods def file and game shouldn't crash.

Give me minimal maps load order which crash.
I need to test your load order and find where is bug.
Promods def should be below because I have latest version of FLD's prefabs unlike promods.

Realistic Russian Highways are not compatible with Realistic Traffic by Cipinho v3.0. When I remove traffic mod from mod list even with Poland Rebuild 2.0 Realistic Russian Highways works fine.

And the reason is: He also modified file traffic_rules.rus.sii. Maybe you can put it below Realistic Russian highways. Try.

Promods version is updated - bug fixed in Better traffic flow.
