* When the cause of destruction was world-induced (CanBeAt check failed) there is no tool. Pass the nullptr directly to ConvertToPickups and let it handle it.
* Fixes#4795
- Remove unused a_Digger parameter to ConvertToPickups.
+ DoWith calls now broadcast the block entity and mark the chunk dirty
+ Add block entity change queue to synchronise BE updates with block updates
* Fixed a few incorrect assertions about BE type
- Remove manual overloads
* BlockHandler initialisation is a constant expression
If we can't make it all namespaces, this is the next best I guess.
+ Tag handlers constexpr, const as needed
+ Inherit constructors
* Privatise handler functions
* More constexpr
