My Sim Keeps Going Through Floor

I rearranged the room moved the bed to.
My sim keeps going through floor. Enabling collision physics allows other objects to collide with the cloth it does not affect the simulation. After changing households the sims teleported inside and the issue seems to be fixed. My sim keeps sinking through the floor to the ground level. I m not too good with technical stuff so i would need some help with this.
I just downloaded sims 4 and ever since i first opened it the screen started flinching from the top. For some reason two doors in the upstairs just don t work my sim goes near to them and does the exclaim animation as if the door were locked. Once the objects is on the floor it can move around without falling through the mesh itself does not have little holes or missing polygones. Sometimes a falling object does not collide with the floor but falls through it.
This happens whenever he eats of clears the table. When you click play after that it should work. This isn t a problem at all. With the locked icon in the speech bubble.
The floor has a mesh collider the falling objects box colliders. Hello my sim has just moved in to one of the ea built houses in willow creek so just being clear there s absolutely no cc furniture in the house. If i disable istrigger for my player then it won t be able to go through the other objects which i need it to go through. I have tried restarting the game and using resetsim.
I tried to fix the problem with origin but it couldn t find the issue. You can use layers to make unity set which colliders can collider with another. First picture shows falling through demo level floor. I don t have any coielings but i have already tried replacing them and the two roofs either side above the bay windows don t go through either even though those rooms don t have a ceiling.
I read somewhere that the problem could be abo. Begingroup you can t keep the cloth from going through the character without enabling collision on the cloth sim. That above is the problem i m having. Endgroup pgmath jan 5 16 at 3 18.
The sims are unable to enter the house through go here or using an object resplacing the door and removing the wall does not fix the issue as the sims are unable to find a path. Just disable the istrigger then use.
