Bridge-building Bug??

[Troll]

Hi Tim. After reading the rules which are below, it seems that maybe you can not up grade to a vehicle bridge while the foot bridge is in place. You may have to destroy the foot bridge first and then have a Bridging Eng come in and build the Medium Vehicle bridge. In other words you are asking the program to put 2 bridges in the same hex. This doesn't seem to be the same as having an Eng unit build an IP and then have a Construction Eng build a trench on top of the IP which does work. This is just my best guess. I tried what you did and got same results. So either destroy the foot bridge and then replace it with a vehicle bridge or move to next hex and build the vehicle bridge.

An Undisrupted, unfatigued fully-supplied bridging Engineer unit may attempt to build a vehicle bridge across a hexside stream or river with a 20% chance of success. The procedure is similar to that used for damaging walls or blowing up bridges. In the unit menu, select Lay Vehicle Bridge, select the direction for the bridging attempt, and press Enter. If a vehicle bridge unit, or light modern MTU or AVLB is making the attempt, there is a 60% chance of success. If successful, the Engineer unit will assume a low on ammo status and remain so for the remainder of the scenario. The whole process assumes that the unit is attempting to construct a medium vehicle bridge using specialized materials that the unit has with it. This means that a bridging Engineer platoon may only build one medium bridge during the course of a scenario!

Bridging Engineer units are specialists. They can only build medium vehicle bridges. They many not build light foot bridges, clear mines/obstacles, or blow up/damage walls or bridges. Any Engineer-constructed bridge can be destroyed by any Engineer unit capable of blowing up bridges. The process is identical to that used to blow up regular bridges.
