In IR2 there remaked tech tree, so there is no technology called contruction robotic like in vanilla. There two solutions, first is no technology prerequisites . Second is more complicated, from my experience you can fix it by adding line to data-final-fixes or data-updates
if mods["IndustrialRevolution"] then
and stick tech prerequisites to ir2-robotower
.
Deadlock did something funky with tech tree and there is need to be these changes in data-final-fixes or data-updates
