Just like title says, custom blocks do not work for me. They are made specifically for TrackMania 2 Stadium but they don't appear in the editor. I followed instructions for mods and unzipped blocks to Documents\Maniaplanet\Blocks and items to Documents\Maniaplanet\Items. Affects any custom blocks that I download, the game simply does not see them unless I am stupid - I only got TrackMania² Stadium today 2021-12-25 and have never played it before, only TrackMania Nations Forever and TrackMania United Forever. Yes, I did search for any topics like this on reddit and this forum, and yes I did look in all items in editor in all categories. Examples of affected sets/items:

• https://item.mania.exchange/set/view/109
• https://item.mania.exchange/set/view/10580
• https://item.mania.exchange/set/view/11160
• https://item.mania.exchange/item/view/17892

Did you get it working by now? Sorry I didn't reply sooner.
