Materials keep vanishing from editor

Hello, yesterday i made some new material in editor and after a while it was not there anymore, so i made it again, today is vanished again,. There is some problem on servers??

…they are back… -_- perplexed…

No problem with the servers that we’ve noticed, no. Let us know if this problem recurs.

Hi Will, i have noticed that it happens when the connection is not fast enough or when the pc is slowed by other programs (ex antivirus) so no your servers fault at all…
