Island Living Build Mode Bugs

@brittsNAY01 I was wondering if this may be related https://answers.ea.com/t5/Bug-Reports/NEEDS-INPUT-IL-Glitch-in-outside-flooring-disappearing-in-Water/td-p/7964479 but the floor disappearing when you place objects on it seems to indicate different causes. You could have a look and see what you think. From the wording on your form I am assuming that you used to have mods, even if they are out of the game currently? With this in mind... 

Unfortunately, last week's large patch/update brought in many changes. These types of changes effect many aspects of the game. Mods and CC involve code that can sometimes clash with the updated game code, and even cause damage, if not properly updated to match the new changes in the game's codes. Even after you remove the Mods/CC, sometimes damage can linger in the game code that can be addressed by removing cache and repairing. I would recommend that you do the following in this order:

• Exit your game then exit Origin. Copy the Mods folder from your 'The Sims 4' folder onto your desktop (for future reference) then delete the mods folder and the localthumbnailcache.package file in your 'The Sims 4' folder and restart the game and so that the game will re-create the folder.
• Then run a game repair [ Open Origin, click 'Game Library' then right-click Sims 4 > Repair Game ]. Make sure to let it run until it has completed all repairs (it will do the basegame first, then run through each of your expansions/packs). After that, please see if the issue has stopped.

If It fixes the situation I would recommend that you check with the Mod and CC creators to see if there are any known issues with their Mod/CC clashing with the update and if so do they have an updated Mod/CC that will address the changes in the game's code from the update. You can then re-add your updated Mods/CC one at a time to see if one was conflicting with the function/causing the glitch - but do not re-add the old config file from the old mods folder, as it is possible for it to have become corrupted also.

Thank you for replying! I suppose I could have worded that better: I use to download mods, but I have yet to on my most recent computer (or at least not for as long time). So mods should have no impact on my current game. The flooring bug seems to be an issue within the latest patch/Island Living

@brittsNAY01 If you are convinced it's a bug you can report it in the bug area. you may need to split the two issues into two reports. In the report you can list specifics that will be helpful for others to test and see if they can reproduce the issue for reporting to EA. https://answers.ea.com/t5/Bug-Reports/bd-p/The-Sims-4-Bugs
