Not yet sure if you're talking about loading the film in developing reel, but I assume that the problem is just this.

Loading the film on plastic reels can be a problem is the reels are wet. A drop is enough to make the wet film very sticky and difficult to advance.

Thick films, like delta for instance, can give problems if the take up spool of your camera rolls the film clockwise (reels usually are counterclockwise). If this is the case: 1) be very careful in cutting the leading edge of the film;
2) do not develop the roll right out of the camera but let it rest in its cartridge for a day.
