You have given me enough information, and it should be fixed in next update. Thank you

Hello! Thanks for the feedback.
Do you have a way to reproduce this bug?
Which block do you use as model for your custom block?
Do you have a .Block.Gbx that makes the game crash every time?

Hi,
This feature will only rebind items that have been moved to a different folder but that have not be renamed. But of course, even if it fails, it should never make the game crash! Can you give me your map so that I can fix this, please?

Here are the exact links in documentation and GitHub for this XML:

This bug will be fixed in next update:

At last I found the time to fix this annoying bug. So, in next update, your custom blocks with grass will stay collidable when replaced by dirt or blue floor.

Thanks for the feedback, it will be fixed in next update.

Can you give me the map please?

Hi
Those maps seem to use unofficial mix-mapping, achieved in TMUF with external tools. In that case there is no guaranteed compatibility in Maniaplanet. Sometimes the conversion might work, but sometimes it doesn't.
