Suggestions on tips to avoid crashes?

Hi all.
With crashing in multiplayer common ATM I thought I’d see what practices the community uses to minimise them.
Was in a server with a player and he dropped into game chat briefly and suggested I remove my waypoint to avoid a crash.
He left chat, probably back into psn chat, before I could ask any follow up questions unfortunately.
That’s all I have been told but a fair guess would be that using game chat and more players in the game would put more stress on the server.

Way points have never been a problem for us on Ps4. But when clients crash it’s usually when we are in a fight. Host can have lag but almost never crashes.

Cool. I’ve returned to the same hosts server so you’ve made sense off that 4 me.
