Wouldnt it be a good idea to remove the cache when someone add or delete a flavor in the stash, to avoid waiting time in case of someone think is might be a good idea checking what he can make half way through adding his new flavors?
Also, it happens quite often that someone add the flavors using wrong naming/abbr, and then have to wait 2 hours after correcting.
I now have the option of making a new account, or I have to wait two hours. This is because I added like 20 flavours and still the same recipes show up. Pretty darn annoying…
