Blocked Players (Cancelled Substitutions)

[Tactician]

I have had similar situation when on Android app - requested substitution of a player who has yellow card, but before sub is actioned, player concerned gets second yellow card and then sent off. Obviously, sub could not be made, but when I tried to change player formation on pitch and try to make another substitution, the app wouldn't let me - the little 'There are unsaved changes' message appears...

It is as if, despite clicking on cancel, it saves the change made, but does not make the actual change, and the concerned player(s) are blocked. This is definitely a flaw. I noticed it on the new browser version. It seems that I may have seen something similar with the previous browser version. So, this is not likely to be new, and it has not been fixed yet.
