V-Ray Scene - Tile Assembly fail

Hey I exported and rendered my scene from C4D n as a V-Ray Scene with the Tile-Option and am running into several problems.

First it did not start at all but this was fixed using the submission file from Deadline 10.3.0.10 Monitor .vrscene from Rhino tile render parsing crash.

And now I am running into the Problem that the Tiles cant be stitched together because of (my guess) a path error. The files are stored on a network drive and the path in the Error-log seems to have a backslash where there should be a forward one.

Error: STDOUT: RuntimeError: Magick: UnableToOpenBlob `//server/_Output_tile0_Test.jpg’: No such file or directory @ error/blob.c/OpenBlob/2964

Maybe you have a solution / ideas?
