No, Sourcemod doesn't have the ability to control flex animations. But it's a request I've been looking at and I'll update it after this week.
I think this may have been posted before, but I've never seen anything like this mentioned on the official https://networkz.com.sg/best-web-des...-in-singapore/
. I understand the problem but there needs to be a better solution or workaround than spamming the bd thread. It was explained that the bugs the devs were working on may be the source of the above problem. Some of the patches have fixes for the bug, but others don't.
