Whenever I try to enter the imperial academy on floor 2 I get the message "File not found: Graphics/Tilesets/HF2_A1_1" followed by the game crashing. I checked the Tilesets file and sure enough it isn't there. Am i supposed to have this file? I just recently downloaded the game for the first time using the most recent update.

Nope, that's me fucking up. Will be fixed in the next version. For now, just copy paste any other of the A1 files in the tilesets and rename it to " HF2_A1_1 " so you can progress (might make things seem a tiny bit weird, but I doubt it, don't think water was actually used in any of the Academia).
