Problems with checking wether a file exists

I've had some problems recently using the File object, and more specifically the "File exists" condition. For some reason, on some events where I want my application to check wether a file exists, it acts like the file doesn't even though it clearly does. I've tried referring to the file using an absolute path rather than a relative, and also doing a workaround by using the List object's "Load Filelist" and then comparing the amount of results, but the problem remains. Moving the event out of a FastLoop seemed to solve the problem on one instance, but it still frustrates me to not know the cause of it.
Does anybody have any idea why my application is behaving this way? I've double- and triple-checked my code and all I can think of is that there's some kind of bug in Clickteam Fusion.

The source code of this condition seems correct. If you think there is a bug please fill a bug report in the bug box with a (simple) MFA file, thanks.

Had the same issue, kinda hard to reproduce. It appears more often if you have a big project and a lot of loops. The File object will exit with error code 0.

Still I found a workaround that worked for me: Instead of the usual loop to ask for a file exist, use the loop from the Fast Loop object. It works, lol.
