In update 5.6.281 i encountered a issue. Before the update i worked with a predefined structure without childs and later in events i used to change variable value/text but now engine cant access it if child is not declared beforehand.
Try
SendJoinRequest_forUser[“type”]
what you just said is an example of what i was complaining here:
that is, is just an UI thing, which could mean one of two things:
or they will rework the way structures/arrays childs are declared and mentioned in future
or was just an bad color decision
