Playing Glacial Awakening, using HWell version 0.4.2. Crystal burst seeds work as intended, however cobblestone burst seeds will properly burst and create item entities that the player cannot pick up. The item entities do exist; hoppers can pick them up and gravity blocks/water can move them. However, the player cannot directly pick them up. Exiting the world and reloading causes the item entities to disappear. Admittedly this issue may be fixed already, but I didn't see anything about it in changelogs, so I figured I'd report it.

I have just discovered this same issue with the VolcanoBlock modpack, but it is the Netherrack Burst seed that generates entities that cannot be picked up. The rest of the burst seeds (including cobblestone) seem to work as expected. Also the entities can't be picked up with an Item Router with the Vacuum upgrade.

I'm also having this issue. Same as OP, I'm playing the mod pack called Glacial Awakening (version 1.1.5).

Playing Glacial Awakening. Version 0.4.2. Same issue with Stone and Sand. I cheated in a Vacuum Chest for now. Netherrack seems okay.

me too on glacial awakening 1.1.7 with hearth well 0.4.2, can't pick up sand, gravel seems fine, haven't tested anything else

I can confirm that this issue still exists in Glacial Awakening even with Hearth Well 0.5.2

Sorry, I'm aware of this issue (although I'm not sure whats causing it because it does not happen with HW alone) but I'm in the middle of reworking most of the mod so there is not much i can do about it right now.

Huh, another player had the same problem but with another specific burst seed. Weird. Will look into it

I am having the same issue, on the same version, except with both the stone seed and the sand seed.
