Short description of error
Baking the ocean modifier only works once, then I have to save, exit blender and then re-open the file before I can bake again.

Exact steps for others to reproduce the error

Open blender.
Select the default cube.
Go to modifiers tab
Select the ocean modifier.
Click the "Bake Ocean" button.
Click the "Delete bake" button
Click "Bake Ocean" again, but it won't work (for me at least).

System: Windows 10 Pro 10.0.18362 x64

Even more: "delete bake" does nothing at all. I even can't rebake ocean.
What have I done:

Baked ocean, saved file and closed Blender;
Launch Blender, open project file, try to delete cache - nothing happening.

Windows 10 19041 64 bit
2060 Super

Having the same problem. I can't delete ocean bake either, even after restarting multiple times and changing cache file path. Ocean modifier will also randomly stop affecting the plane in the viewport (so that it looks like a flat plane again) and I need to restart to get it back.

Windows 10 19041 64 bit
Blender 2.91.0

Having the same problem. Also when I duplicate the modifier, the new modifier is marked as baked.
After the first bake of the new modifier, without saving the blend file, I could delete the cache, but not rebake it. After saving and realoding the file I could bake and delete one time again.
If I bake, save the blend file and reopen, there is no way to delete the baked cache.

Recreating the modifier from scratch is too hard.

Is there a workaround?

I found sort of workaround: just change grid resolution, and Bake will be live again

Thanks for bringing this up, I had the same issue.

After much trial and error, I found that changing the "Spectrum" automatically deleted the previous bake, allowing for a new bake immediately.

Spectrum being the option above bake "see screenshot".

I switched to "Established Ocean" and then back to "Turbulent ocean".

EDIT I am not certain that this works all of the time.... It's a few hours later and I am experiencing mixed results.
