Character instance respawns randomly in multiplayer mode

Hello there again. Have one more problem in multiplayer mode.
Sometimes my character instance respawns in multiplayer mode (both on server side and client side). I tried to record the demo video with that bug:

Here as you can see, other’s player character freezes for a moment, with reseting animation BP (also on a client side compass resets quickly at this moment). It already was a 13th instance of the KeryBP class, and after the glitch it became KeryBP_C_14, so after that my widget BP hasn’t seen it. It happens fully randomly, and I couldn’t find anything what can cause such bug.
Did anyone meet such problem before? What could cause such respawn of the character instance? Thank you for advance.
