There may be a similar issue with other tools' secondary abilities, but the pickaxe was the tool this was seen with.

Spectrum adds ores that cloak themselves as stone/deepslate if you haven't unlocked them. If the block is locked, it drops stone/cobblestone, if it's unlocked it drops the gems/ores etc as it should.

When using the vein mining ability, the spectrum blocks drop as cobble even if they are unlocked to the player:

• Anticipated result: They vein drops the ores.
• Actual result: Cobble dropped

Looking through the source, BlockCrawler appears to the be source of the issue. the BlockBreakingEntity calls crawl when it hits a block, and the BlockCrawler makes its list of ore blocks and then calls on WorldOps from owo-lib to break them. The issue is, the player context isn't passed.

The BlockBreakingEntity has the owner entity available, so I believe that the BlockCrawler needs to accept and store the owner entity (or null if not available) in it's CrawlData to pass it as the breakingEntity to owo-lib.

From owo-lib, circled method is currently used. breakingEntity is needed as context:

Even though I forgot to mention it in the changelog, this has now been fixed in 1.0.28
