What you were expecting to happen, and what actually happened
After testing my PVP defense team, the victory screen is showing gold rewarded. I was expecting no rewards since I was testing my own PVP defense team.
How often does this happen? When did it begin happening?
I tested it about 4 times and it happened each time I won the match. I believe it may just be a visual bug because I checked my gold after each match and I am not receiving the gold shown as rewarded.
Steps to make it happen again
Simply test your PVP defense team.
Ever since I can remember, I never received any gold when testing my PVP teams. I made this bug report because I believe it showing that I was rewarded gold is the bug. I believe I should not get any gold for testing my PVP team.
