Fluid Sim - Issues

I recently decided to create a waterfall simulation in Blender only to go half the way and be forced to stop. I've created the path which the water will follow from a plane and set it as an obstacle but no matter what I do the fluid keeps passing through and instead colliding with an invisible shape. No matter what resolution I've tried it refuses to work and I am on the brink of giving up. I have tried all three obstacle type options to no avail. I end up with the fluid becoming this as though there is some other object.

I thought maybe the fact that the path was a plane the fluid was passing through it so I used the solidify modifier and yet it still passes through. If anyone wants the file email me and I'll answer back. If anyone has suggestions it would be great.

This is what was happening:


I exported the ground as an obj file then imported it into a new file, went into edit mode and pressed several different things which solved it but I retained the original problematic file because I want to know what the problem could've been so that if I ever come across it again I don't suffer problems.

I'm completely new to this so how would I do that? I can't try it right now but I will later.

Thanks!

ctrl+A. Apply them one at a time and see if they solve your problem. I say start with scale then rotation and then location.

Also, find out where it's writing the cache files. I've had this happen, and have had to trace the cache files to a temp folder in some AppData folder that was hidden (on Windows). Find that cache, delete it, and see if it helps.

I didn't want the fluid to be cached in some random place so I changed it's directory to a folder that is in the same folder as my .blend file. I deleted it's contents but that still didn't help. I'm going to try ChukChuk's suggestion once I am done with my fluid simulation. (Left it on overnight AND still not done)
