[kovarex][2.0.9-1] "Transport line groups are not consistent"

[EpiXz]

Today I wanted to continue playing my Space Age save wich i already have 33h in but for some reason today i cant load into the world and get the error message "transport line groups are not consistent". This also happens when i try to load my last 3 autosaves. After some browsing on this issue I was able to load the save file again while holding the ctrl button while pressing load. Afterwards I just saved the file under a new name and now it seems to be working again. I will attach both save files, a picture of the error msg and my log files in case devs wanna look into this.

Thanks for the report. Do you know what has happened near the position 33.5,-409.5 (attached image)? Ignore the stack of items, thats an artifact of transport lines deserialisation when belts failed to connect properly.

You can temporarily fix this save file by holding Control key while pressing "Load" button and then saving it to a new save file, then loading that new save file it should be working fine.

I had the same error in my world, and I've found steps to reproduce the issue. It seems to be caused by underground belt placement logic with obstacles in specific places.

-Place obstacles and belts like so:

-Drag a line of belts from the bottom to this tile:

-Note there's a second belt placed under the first. Saving and reloading still works fine at this point, it just deletes the belt underneath.

-Rotate this belt, and save. Now the save file causes the "Transport line groups are not consistent" error on reload.

I've attached the minimal broken save, and the log.

Given that reproduction is valid in 2.0.11(under development) and it being related to manual building, i am assigning this to kovarex.

Likely related issue. 2.0.8 Stable has been our playthru for the last few days, until tonight when I attempted to login (while others were playing) only to get that error message upon login. As others exited the game to verify the problem, they had the same issue. I took the server down for upgrading to 2.0.10. We run a manually installed, dedicated server for a small group of about 5 players. Up time has been about 3 days.

Upon first boot, I logged in successfully. I was the only one on. I started planning Gold Science and used the upgrade tool on our bus lines to start prep. Shortly after, I noticed the upgrade icon over what looked like blue belts here and there where that icon should not be. I then desync'd out (which is highly unusual) and could not login again. Starting the server now gives the included error upon start.

Hello, thanks for the report, this is now fixed for the next release.

If you want to do a quick and dirty fix, until an update is released that fixes this, then launch your broken save by pressing Control while pressing "load" button, and then finding the broken transport belts by going into your log file which has the coordinates of the broken belts. (you can find your coordinates in game by pressing F4 and selecting "show-detailed-info")

Then just go to all the broken belts, remove them, and then save again, and load the new save.
