Warning: Assembly BigDaddy-***.net.dll has been loaded into the mono rt2 runtime. This runtime is still in beta and shouldn't be used in production, crashes and breaking changes are to be expected.
If you see the warning above in your client or server consoles/logs, do not be alarmed. There are two versions of the Mono implentation into FiveM. This is how the C# resource works with the game. The V2 version was created by CFX and it has not been officially released as of yet. CFX still points people to the V2 version to use as it is MUCH more efficient than V1 for C# resources. When I say MUCH less, I mean there is a huge difference in how much CPU is used between the versions.
We have started to move all the scripts to the V2 version because of this. Since it is techincally still in beta that message displays. It's a disclaimer from CFX about it being in beta still. The trade off in beta implentation vs. CPU/performance gain was well worth it. You can safely ignore the warning for these reasons.
There are some game builds that do not have rt2 enabled. 2944 is one we know for sure. 3095 DOES have it enabled so beware you might have to change game builds to load rt2 scripts.
