This seems to be a random occurrence, but others on Unreal Slackers discord seem to have had it occur to them as well.
Sadly, I cannot reproduce it. But please see gyazo link:
specifically this part:
Right-clicking and hitting refresh nodes, takes it away though.
Hey -
How are you creating your struct / blueprint node? Was the struct created in code or through blueprints? Are you adding a variable of the struct’s type to your blueprint? Also, the node in your screenshot does not appear to be a standard “Break Struct” node. How are you creating / adding this node to your blueprint? Lastly, what kind of blueprint are you using this in (Actor, character, scene component blueprint, etc)? What were you working on when you noticed the string of numbers? For example, did it start to occur after compiling the blueprint? Let me know what you have tried so fart to reproduce the issue and we can go from there.
