Hello...
So, I had done a complete un-install/re-install of the sims3, along with world adventures, I have *no* CC whatsoever in my game right now. I played it yesterday, and earlier today just fine... however, after trying to load up the game again, I now get this new "Installation verification failure" message. at the main menu. It says something about the installation being "Incomplete" and to "Reinstall and try again".
Edit: after un-installing and re-installing it fixed the problem, but then The error happened again, and had to reinstall. I'm not sure what triggered this. Although, it first started happening after downloading an EA tool, while i was reporting a bug, (It was supposed to be like a compatibility report or something, in which i was supposed to send it back to them) not sure if that was coincidence?
Also while I'm at it, to save space, i have on more issue I thought I'd ask. Again, I have *no* CC at all in my game. But since installing world adventures, after travelling on vacation for the first time, there was a loss of all base-grass textures. (Where grass was supposed to be, it appeared black, and after zooming out, and in again, it showed up as a flat solid green blurry type of thing.) still had that problem when my sim arrived back home again. (The grass detail was there before travelling) Graphics are on the highest settings. And since there is no CC, not sure what this could be.
Edit: Now the problem has spread to roads and sidewalks being completely blurred. I uninstalled/reinstalled, didnt help.
Here's a screenshot of how it looks in game, highest graphic settings. (oh, in this pic. you see grass detail because I used terrain paints. The actual "Base" grass detail is gone, as you can see around the edges. (Again, texture detail is at highest setting)
