I am having an issue with projectiles on my map

[LordDickinsonIV]

So i am having an issue with my map when someone is on a team (blu or red) and someone else connects. Once they connect and are put onto the motd screen all projectiles break or basically they don't explode when they hit walls or people.

We have tried turning off any plugins we had installed on the server to see if those were causing it but it was still happening.

Here is a screenshot of what is happening: https://i.gyazo.com/5ce98ca0859a6eb5afe13021e0709c2c.png

Ip of the server we are having the problem on: 158.69.83.37:27016

If you can help me with this it will be greatly appreciated.

We've had somebody else with the same issue recently.

Does it only happen on a certain map, or all maps?
