Updating from 2018.3.11 to 2019.1.8f1 Problem

Hi!
After updating i'm having problems with run-time loading png images. I use a palette swap shader that swaps exact colors for other colors... this tool still works but it seems like previously working swaps broke and need to be redone. This is a problem because there is existing content for my game that cannot be updated.

 

Well, then load back your backup and continue using 2018 unless you have a really good reason to update.

Also General Discussion isn't a support forum, if you have questions about shaders best you can do is ask away in the Graphics forum.
