Hello again, Ranko fans!
We've received new reports about the previous issue related to the flash effect, that now causes crashes even when turned off, so as a precaution we have decided to eliminate them completely, at least until we can find a definitive solution to the problem.
Also, we've fixed some more typos, mainly on the english text (we're not native, sorry.).
Again, thank you for your patience in our first foray!
