I played yesterday and went mining.... I could not break some blocks. Anyone knows why??? Even in my city some type of blocks can't be broken.
This is a bug with 1.20.3 clients, see: https://ecocitycraft.com/forum/threads/cobbled-deepslate-bug.224673 & https://ecocitycraft.com/forum/threads/cant-break-stone-blocks.224671 It seems to have been fixed however, so I would comment on one of these if you're still having the issue
