Issue joining servers: Too many pairs created, new pairs will be ignored.

Servers are listed normally, but when I attempt to join one, nothing happens. There’s no crash, no nothing. I click the server, and absolutely nothing happens, apart from a small error appearing in the console that reads “Too many pairs created, new pairs will be ignored. This is perhaps due to an excessive number of objects created at one location.”

I’ve seen others with this issue, but as of yet nobody seems to know how to fix it. Any help is much appreciated, thank you!

Edit: After a few attempts at fixing it myself (to no avail) I realised the error actually occurs when the server list is loading, not when I attempt to join a server. Still have no idea how to fix it.
