Status: Pending

Reported: Oct 23, 2026
Seen in version: 0.1.8.24 and earlier

What happened: Research that should raise a tower's reach does nothing: Tesla Arc Distance, Miner Excavation Depth and Airport Extended Patrol.

What was expected: Each level of these research items raises what its description says.

How often: Every time.

Where it stands: Fix in progress for the next version.

Fixed in 0.1.8.25 (Oct 23, 2026, 8:53 AM Eastern).

Tesla Arc Distance now raises its range and how far its lightning jumps, Miner Excavation Depth raises its depth, and Airport Extended Patrol raises its patrol range. Research you already bought works at once.
