BUG: Fish disappear from the inventory

Problem
I was traveling and caught some fish that is only available in foreign towns but when I came back home, the fish (and possible other objects) got missing and can't be found in the inventory anymore.

Cause
Because of an error in the code fish cannot be recreated properly after traveling. This also causes to bounce most other objects in the inventory.

Solution
Use the cheat buydebug to place fish spawner in your home town. This way you can at least finish any open opportunities. Make sure you don't have fish in your inventory when returning home to make sure that everything else gets home ok.

BUG: Spiral Staircases don't work anymore

Problem

• The interactions use stairs is missing
• My sims takes to stairs to go up but can't go back down anymore
• My sims can't use the stairs at all anymore

Cause

• Patch 1.26 made the interaction disappear. As soon as you install Pets, it's back, but only if you are on the same lot as the stairs.
• Since Patch 1.26, existing spiral staircases tend to be a bit wonkey. 

Solutions

• Sims can use the stairs if the interaction is available or not. Just click on a square next to the stairs and they will go up/down.
• In most cases, it's enough to turn the stairs a little to make them usable again. If you build walls or small stairs, you might need to do some rebuilding. If any of your inactives live in houses with spiral staircases, make sure to check those as well. If Sims can't use those, that will lead to lags cause they will be trying over and over and over if they are pushed to do something
• If you are using non-EA stairs, make sure to update those.
