engineer.lua is causing a crash
In the Factorio 2.0 update, the game developers renamed the maximum_wire_distance property to wire_max_distance across entity prototypes. When the mod attempts to check a power pole's wire reach using the old name, it searches for a non-existent key, causing a non-recoverable Lua script error
On line 472 you have
local reach = math.min(pole.prototype.maximum_wire_distance or 0, candidate.prototype.maximum_wire_distance or 0)
This should be changed to:
local reach = math.min(pole.prototype.wire_max_distance or 0, candidate.prototype.wire_max_distance or 0)
