Visit-type task was a contribution from Arszi's task pack. The core idea is simple: there is a list of objects, and you need to get close to them. In this case we take 3 random smarts from current level - ?$ macros ensure all three exist.

GEN field is a special thing called generator. Its purpose is to take one entity and create more of it. I use igi_generate.Split to split a list of ids into single entities, each of them having only one id.

"subtask": true is an experimental WTF feature which allows for a single task to have multiple task markers on a map. I want to keep it one way or another, but I'm not sure if I'll keep the current implementation/API.
