I have multi-tile stations where some of the tiles need custom foundations, but some should show the default foundations.

Now, the spec for action0 stations, prop13 says:

"3 8 Use custom foundations on sloped tiles (the lowest byte of var. 10 is 2 for foundation sprites) [...]
Bit 3 works somewhat similarly to bit 0: your sprite selection will be called again, with 2 in the lowest BYTE of variable 10. If the chain ends on a callback result, TTDPatch will assume the foundation selection has failed and will use the default foundaton sprites. [...]"

This doesn´t seem to work in OTTD. Instead, some random sprite is shown for chains ending on a callback result, instead displaying the default foundation.
