Unity Cloud Build Not Including .so Files From x86 and x86_64 Directories in Repo

In particular, these are the Steamworks.NET plugins. Here are the files on my local:

Here are the files in BitBucket:

And this is what shows up in the compiled cloud built project:

If it helps, here is an example of one of the plugins in Unity:

I wasn’t able to reproduce this problem using a mostly empty project that just includes the “libCSteamworks.so” file, setup the same way shown - placed in “Plugins/x86” and marked for x86 only. Building for both linux x86 and linux universal showed libCSteamworks.so in the Data/Plugins/x86 folder.

What version of Unity are you building with in Unity Cloud Build? And locally? And just to rule it out - have you tried running a clean build in UCB?

Thanks for trying sir! I have another project with the same files that included them with a new Linux target I just made. I’m going to look into it a little more and I’ll get back to you if I can figure out what the difference is.
