## Meaning

a behaviour called `entity.visible = …` on an entity with no mesh or sprite, or `ctx.ui.set("screen:node", …)` on a screen that is not on the stack; the call did nothing and the behaviour kept running; said once per entity or screen and call per session

## Fix

add a mesh, hide the mesh child instead, or push the screen first (`ctx.ui.stack()` says what is up); a wrong node on a screen that is up still throws `ui.set.unknown-node`
