Bug verified on WinUAEX.
This is how it happens.
Pick a HDF game and open it.
Watch the "workbench scrren thing" and all the loadings process.
When you finally reach the game main screen, do a SAVE STATE and exit the game.
Next, go to the emulator settings and turn ON the feature "Auto load most recent save state".
Enter on the very same game, and ta---dá, you will be right on the game screen, skipping all the boring loadings.
BUT - now press the ingame menu and check what is inserted in the disk drive 1 of the emulador.
Instead of being the "game name.hdf" you will have some broken text, some gibberish.
However it is important to note that this happens only when you use the AUTO LOAD.
If you enter in the game and load the STATE manually, no problem happen.
Also, there are bad results with this bug when you are playing a multi disk game.
I don't know if I was lucky or what, but with single disk games the bug does not affect
anything, since the disk is already loaded (I think).
But anyway - at any moment when the emulator gets the need to load anything from
the disk it will not work. At least the WinUAEX does not crash, it just presents no results
on the screen, and to correct, you just need re-insert the correct disk, removing the gibberish'ed ones.
I hope my description was useful for you guys, to correct this in the future.
