Replication Bug ?!

Hi, yesterday I was working on my project I tested it just before I closed it it was working very well ( replication too ) !

Today when I opened it the server working well good but the client doesn’t show the widgets created by a trace line hit,
play the wrong animations ( for example : play aiming run animation when sould play aiming walk )

I readed my blueprint a lot of time I did tests with print strings for example the speed in animBP is true for the server but is false for the client.

I just change few bp nodes that doesn’t matter like delay or things like that I don’t know what happend.

Thank in advance for any help.
