Using the line "on rightclick on chiseled_bookshelf" results in the error "Can't understand this structure: on rightclick on chiseled bookshelf"

if event-block is chiseled bookshelf:
it does work fine.
In the Discord it got said it is eventually a missing alias.

Using the line "on rightclick on chiseled_bookshelf"

Have you tried without the underscore?
Skript currently does not support block data in click events, and aliases do not have underscores.
You said if event-block is chiseled bookshelf: works fine, which tells me the alias is in fact there.

Even if the alias were missing, Skript auto-generates missing aliases.
This tells me that the issue is due to the underscore you have in the event.

Hey, to confirm I tried each variant again:

chiseled_bookshelf:

chiseled bookshelf:
seems to work this time, yesterday it did not, as seen in the error I posted previously in discord aswell:
[23:50:52 INFO]: Can't understand this structure: on rightclick on chiseled bookshelf
[23:50:52 INFO]: Line: on rightclick on chiseled bookshelf:

But trying it again now seemed to work, maybe a quirks and a restart fixed it I suppose? Either way seems to be solved, so I close this, thanks tho!:)
