Hey!
Me and a couple of friends are working on a party game in Unreal Engine. We understand replication pretty well and are able to replicate certain mechanics. But we cant seem te replicate our dash. We have been stuck on our dash for weeks now.
It works well for the server. After we tried to replicate it, the clients could also dash but is was more a teleport then a dash. In engine with no simulated lag it does work. But when we simulate having like 20 or 30 ping the client just teleports.
If someone could help us through this post would be great, but if you are someone with multiplayer experience that would love to help the project, we can even add you to our discord yo ask you for help whenever we are stuck again regarding replication.
At this point we are so desperate that we would even pay a small price if someone succeeds in helping us. We would be so happy if we get it working and understand why its not working 
Anyway, we also included our code and a link to the video of our issue,
Thank you!
