I’ve got some `for` loops which sometimes change and sometimes do not change if code written in `Blocks` goes to `JavaScript` mode and back. When multiple `for` loops with `value` are used, _sometimes_ these get converted into unique names, e.g. `value2` and `value3`. I have a case where the “unique-ifier” has done a half-job and performed a partial search-and-replace on the usage inside the `for` loop.
It would be interesting to hear if others have experienced this and if anyone has worked out when this bug strikes?

Could this be partly related to using the `sprite x` block on a tile? That’s been working for a while but that’s what failed to convert from `value` to `value3`.
