Hey @Contrary .
Thank You for answer.
Issue happens when my choice scarf is changed for weakness policy in pvp ranked battle by trick move. Im loosing choice scarf when this weakness policy will be activate by supereffective move. I bought 2 more scarfs, last time i was playing with team with 3x trick and 3x choice scarf (cofagrigus, rotom and gengar). Yesterday it happens again on Cofagrigus, so now i have 2 choice scarf lost by this bug. This bug in 100% is connected with trick/choice scarf/weakness policy/superefective move. I know because yesterday i was watching carefully what will happen after weakness policy use.
When weakness policy is used, icon of it is hidding from pokemon list. The same happens when you have weakness policy from trick and thats the problem.
Please help. I will checking forum for answer.
