[Mighty Script] When "Immediate" is checked on a Show Custom Subtitle action, it can only ever play once.

Bit of a weird one this. I can supply a map file if you want, but the basic gist of it is this:

1. Create a script with a simple trigger (e.g. click on a specific block) and the action Custom Subtitle, Immediate: Yes.
2. Create a second script, similar except linked to a different block and with Immediate: No.
3. Export and test. The first subtitle will only be displayed once, when you first click the block. The second subtitle will be displayed on every click.
