I got a serious issue here with Steam:
Tonight i needed to update the game. The game runs on the newer NW.js 0.13 a7, which has a file "nw.dll", which is essential to run the game. It is a fairly big file, 66mb for the 32bit version, 87 for the 64bit one.
The problem is, whenever i upload the game on Steam, it doesn't show on the builds list, preventing me from updating the branch. I've tested and figured out is the nw.dll file that causes the issue, as if i remove it from the files list, it uploads everything normally.
I can't even revert back to the previous version of NW.js, as the new game update relies on the new NW.js.
Is there anything i can do? I'm missing a deadline here and dont want to disappoint the users!
UPDATE: fixed by removing all old builds before uploading the new one, as it makes a checksum and the old files probably corrupted it.
