I've noticed when you invent mountaineering (walk on mountains) and then get Algebra (able to found cities on mountains) you can build on mountains, however if you invent Algebra first and then mountaineering you cannot. what is the trigger using/building on mountains? Is it another technology? Cause switching the tile makes them accesable already with mountaineering.

Using the worldbuilder and removing algebra then adding it back fixes it. Seems you need both techs but finding algebra first causes and issue.
