I started seeing a new error this morning while attempting to make some local adjustments:
Loading Error – Correction failed on the execute stage
The error seems to occur only on the brush correction, and not control point or graduated filter. It occurs on almost every file. However, everything seems to work, and the masks are applied as expected. I can leave the image and return to it, and the masks are still there.
PL 4.1.2 build 48.
