Construction robots can build/mine more builds at same time. 1 block each technology level.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
When BCR calls entity.revive() and entity.destroy(), it must pass the flags to raise the appropriate events (https://lua-api.factorio.com/latest/LuaEntity.html#LuaEntity.revive). Otherwise the scripts of other mods won't get executed, which breaks those mods.
Fixed. Thanks for report!
