Hello,
I work to made a big Minecraft 1.12.2 questing modpack and, for somes quests I wonder if is possible for you to add Block Placement Tasks, question to made quests like I imagine and verify the fact of the player realy place it in the world... I know that it is a possible thing to check, because Triumph already allows it for the creation of advencements.

Please let me know if you think you can add that feature for me or not?

Thank's

I'll consider it in future but it will have to be after the databases have been optimised and rewritten. Doing structure validation scans on servers every time a player places a block could get taxing on TPS and the current system's inefficiencies would not help in that regard.

Without validate structure, is it really heavy to just look if the player place a specific block in the world? For sure if you need to look for complete structure each time a player place a block, this can cause lot of lags... Is it more complex to look if player place an item in the world, than look if the player craft something?
