some modders don't tell that mod is updated.
Yeah, it's tricky. Most of them go back and edit their original post, in this case here:
https://f95zone.to/threads/u4ia-ep3-11p-driftygames.158858/post-10702725 But that does not provide update notifications if you edit a message, you can see it was edited last Friday. It does simplify that there is only one post with the most recent version, so you don't get people downloading ancient versions of the mod by doing a lazy/partial search.
I'd posted a bug report about the mansion, he added a very quick reply to it saying it was fixed, which the notification should have shown up as an alert if the thread was watched:
https://f95zone.to/threads/u4ia-ep3-11p-driftygames.158858/post-15814152. But then, even still, you'd need to go back to the original mod message to find it.
I generally follow the Mod link on the first page, and then look at when the message was last edited, in this case last Friday. So something was fixed, and some modders will post what was fixed or added or removed. If it's newer than the one you have downloaded, it's worth a download.
