Today i upgraded Elhain to 5th star using 4 junk "unlocked" heroes. Heroes i lost has been locked to avoid to use for error and because i needed two of those to complete an "Artifact Mission".

Before bug happend i simply used to play as normal, playing campaign. Anyway 3-4 times the game lost connection, also if my data mobile was always working well, without give me any problem with other apps.

I lost the following heroes

Heiress, level 30

Maiden, level 30 (with gloves atk%, armor atk%, boots atk%)

Retainer, level 30 (with gloves atk%, armor atk%, boots atk%)

4 heroes 3 star blue (i don't remember which because was just junk)

3 heroes 3 star green (i don't remember which, because was just junk)

EDIT: Checking now i see items with atk% are back in my inventory. This (over the lock!) exclude heroes has been used to upgrade or level up other heroes.
