My issue is a bit weird. I've been trying to use industrial renewal block in world generation which looks like the follows:

The problem is that, as you can see on the screenshot, all stairs pointing south (industrialrenewal:catwalk_stair) was instead pointing north (industrialrenewal:catwalk_stair:2). All other directions has no problems.

I've tried to specify the meta to be 0 in worldgen config, but it does not work. I guess it might be related to defaut blockstate?

So I wounder if there is anything that can be done on your side, thank you!

industrialrenewal:catwalk_stair@0 is south and @2 is north I do not know what could be happening.
i spawn with command /setblock x y z industrialrenewal:catwalk_stair 0 and its point south
/setblock -448 3 1226 industrialrenewal:catwalk_stair 2 points to north
can you send me the command you are using?

Thank you for the reply, this is getting mysterious.
Actually I've been using Mcjty's lost cities for generation, will do some more investigation
