Changes:
- Delayed pump and red-splitter item as requirement appearance for quest structures (now they shouldn't appear on 2nd or 3rd islands).
- Increased amount of fish caught by all fishing classes.
- Made disband crew button disabled by default
- Disabled instant concrete research and enabled crafting of it (this means nuclear buildings are now craftable and obtainable).
- Blue belts in mazes (and other minor structures) now can be rotated.
- Removed discord message "Difficulty changed to ...".
- Added explanatory text that deckhand and boatswain classes don't generate ore while at sea.
- Increased respawn speed boost duration from 17.5 -> 20 secs (This change mainly targets cave island, but a welcome change to other islands too).
- Fixed rocks giving far more ore than intended in cave island.
- Fixed cave island always having the same layout.
NOTE: Some changes mentioned here are from "test_commit"
Changes:
- Made quest structures return random requirement item when raffle returns nil. This happens because some items have negative weights in lambda raffle.
- Added Cave island to B and D island categories.
