Is the bug with farms converting to special sites still there?

[gunnergoz]

I've had two crashes in two games, each with unusable autosaves, from what appear to be problems when I tried to convert a farm tile by means of a Great Person, into that person's special structure. Most recently it was a Great Merchant settling on a farm. The event happened at the end of the turn and before the turn ended, the game crashed to desktop. The turn's autosave was not viable and crashed when I tried to load it.
Anyone know if this bug was supposed to be specifically addressed in the last patch?
