placing 2 way chain signals on diagonal track with blueprints can sometimes give the signals a block of only 1 tile long and not reporting or retriving from the next signal only breaking and replacing one of the pair will resolve the issue of the one tile long block

Would you happen to have a savegame with that one-tile block, or a way to reproduce this problem?

place the blueprint or create one with dual diagonal chain signals and place multiple times you will get error randomly when placing dual chains on the diagonal
i have placed 3 copies of the rail near the location i am standing when saving this game one of them gained the error 1st and the others did not

note: mods list will be added in 2 parts next post since i keep timming out on the upload

version 1.0.6 is curerent i am on 1.0.5 of that mod

i just noticed taht you can also reproduse it my removeing the rail and replacing it on the diagonal taht is a 100% fail rate
for both chain and normal signals

I also encountered this behavior while doing test on this matter.

yes it almost looks like the same error expecialy that last part where you place the strait rail and it kicks the signal offline ... if the devs think they are related they can merge the posts

EDIT : added video of a recreation at 100% of the bug for all signals on the diagonal

Thank you for the report, this will be fixed in the next patch, but for newly placed rails/signals only, you need to replace the existing problematic ones.
