Those are both very good things to point out.

I think it's important to note though that the draisine and house tracks came out very well in advance of the rail system. Everyone who was interested in using them for inside houses had already bought one by the time the rails came out. But when the rails were completed, the people who were not previously interested in the draisine bought it to travel around the overworld with. Those are the people who got screwed and stuck with an item that they had not wanted to buy for months prior to overworld functionality.

And yeah, they replaced the sprite on your draisine with a newer one (oh yay.) But just in case you might want the old one that you originally bought, the powers that be will allow you to repurchase it for only 4000 gralats again! Thank you based Graal!
