I've noticed this while using "Snow Aware Arctic Buildings v1.0" (attached) but I suspect a more general problem. This grf modifies the default arctic buildings but only with regard to snow awareness, it does not modify availability years and these should be inherited from the substitute building type. There are nine buildings available from 1930 onwards, but when starting a game earlier than this only six of them appear on the map. I've attached a screenshot of the three missing buildings as well as two save games, one started in 1929 and the other in 1930.

The only common link I can see between these three buildings is that they are built in town zone 4. I *know* this wasn't a problem when I created the grf back in April this year. I've managed to check for this in two older version of OTTD, I can confirm that the bug is present in 1.1.1 but not in 1.1.0.
This task depends upon

This bug is also apparent in other grfs such as TTRS.
