Movements are broken with no changes to an Actor

Hi All,

Can someone help me to understand the following issue:
I have a Unit that suddenly starts moving in all directions at the same time and cannot move straight with no changes to the actor or animation BP.

From debug, I can see that Units speed updates each frame and jumps between 20 to 120 (120 is what I set up and was working fine till yesterday)

I have a video for a better explanation of the issue.

I someone can point me where to search it would be great.

Thanks a lot.

I have found that the issue caused by a Static mesh in hands of Actor and force it to recalculate Path. After disabling collision with static mesh issue is gone.
