Oh interesting, what does SpawnPizza() do? does the "dt" method still work in this scenario?
... never mind ... after testing everything again I found the problem was coming from somewhere else. It's weird that it didn't occur in editor until after building but hey /shrug
the dt method appears to work in editor and build but tbh I'll prob remove that one because it's one of the overlapping methods I built before I really understood what was happening when and how - it was a method used to disable the dialogue box onscreen
