Troubled ferrying infantry ...

[Mr Grumpy]

Yes, so in the case of a hexside river taking the engineer units out of bridge ops may not cause any delay in building a bridge (based on a % chance), however in the case of a full hex river pontoon bridge if your unit has been building it for 8 moves and you removed the bridge ops (to ferry units) the pontoon building count goes back to 0. :rolleyes2:

So it is OK to ferry units on the first move, but as soon as you start building the pontoon bridge you need to use another engineer unit to do the ferrying, of course it is always possible you don't have two units and in that case you will have to make a choice. ;)
