Images in a sequence path for an Img Media Source are not updating without restarting the project. Changing the path itself appears to work as expected.
Tested in versions 4.22.3(CL 7053642), 4.23.1(CL 9361420), 4.24.3(CL 11590370), and 4.25.3(CL 13942748).
Issue does not appear in version 4.22.3; appears in version 4.23.1, 4.24.3, and 4.25.3.
Result: When making changes, the the previous image remains in memory and does not change immediately. The project must be closed and reopened for the sequence to update.
Expected: In engine version 4.22, if you replaced the images in the file path, it will change immediately. The project has to be closed and reopened to update in versions 4.23-4.25.
