no loot when brush used on suspicious sand or gravel

Put the summary of the bug you're having here

What I expected to happen was...:
While in Trails and using brush on suspicious sand or gravel, to have loot "poke" out and then into my inventory.

What actually happened was...:
I would use brush, the surface of the sand/gravel would start to change as if it was going to reveal loot, then turn to non-suspicious sand/gravel. No loot. However, if I break it, it makes the sound of the sherds breaking. 

Steps to Reproduce:
1. Go to Trails ruin
2. ...Find suspicious sand/gravel  Unable to render embedded object: File (2023-04-20_16.24.13) not found.|thumbnail

3. ...Brush sand and it will shift to regular sand !2023-04-20_16.24.13!thumbnail
