I have just uploaded my finished version of Perfection ( 4 perfect ratings, read 'em and weep) and if you take a look at it you will see many things going on that shouldn't.
1. Black holes are all over the place, some as a result of attempted overlapping farms, but others crop up in housing blocks.
2. Disappearing buildings, some areas of the map can be built on, but when you go back to the same spot they have gone, but will allow you to build on that spot again.
3. Partially disappearing buildings, same as 2. but remnants of a 2x2 or 3x3 building will not let you rebuild until you delete the remaining squares. (this happened to the storeyard in the bottom left corner)
4. Overeager farmers will carry on sowing even though the inundation has started, if the flood is good they drown, but if it is poor they will carry on to the next flood even if 100% has been sown.
Anyone seen these before?
