We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi, you might get an overflow or memory error. The reason the help says "Note that a maximum of 4 child droplets may be generated with the child generation model." is becuase PT_WALL_SPLASH chops the single return array into chuncks of 4 as RET(1,1), RET(1,5), etc. You could chop it into larger chunks but it is not clear to me whether sufficient memory will get allocated. I am waiting for the developers to get back to me.
