Hello. After updating app to 1.13 (Android 9) I have seen this visual glitch with Relickeeper.

1) Battle speed set to x2.

2) Relickeeper attacks with default skill.

3) Instead of moving in front of the enemy and attacking, he overlaps the enemy. It doesn't have any other effect, it is only a visual issue.

In previous versions of the app there was another visual glitch with relickeeper's attack animation. He moved way beyond the enemy position. This happened infrequently.
