Ah yes, that might be it. If so, it wouldn’t be Monarch causing it specifically, but rather any message.
Searching the forum it looks like the “set_speed” message is used in some Defold tutorials, and maybe in other Defold users’ projects, so it would be strange if this hadn’t been flagged before.
Which Defold version introduced the sound speed parameter?
Ps. If this is indeed the case, is there a list of red flag message IDs that shouldn’t be used for arbitrary messages? I think set_enabled is one?
