MonoRT1: [...] cannot create a delegate on private/internal method [...] ().

[Keyinator]

What happened?

For some reasons private/internal methods cannot be accessed anymore on MonoRT1 which used to work before.

Registering Tick failed: System.MethodAccessException: Transparent method CitizenFX.Core.BaseScript:InitializeOnAdd () cannot create a delegate on private/internal method GamboCityClient.AntiCheatModule:DelayedTicks ().

Additional information

Reports have started today and the issue only occurs on the canary (aka. "Latest (Unstable)") branch

[DaniGP17]

I think is caused by this commit: 32090c7

[DaniGP17]

Already reverted in cc97bd6, this issue can be closed I guess

[iridium-cfx]

Yup, this should be fixed.
