[FIXED] Pizza can't delivered properly if porch < 4 tiles

Same issue on that lot with Welcome Wagon and when Sulani neighbors came to visit. 

If my Sim was outside he could greet them. If visitors were standing on the porch he could not greet or interact with them. 

Same issue and lot. My sim was unable to Take Pizza from the pizza deliverer standing outside the door on the porch; but waved their arms and had a lock in a bubble. When trying to Invite Neighbours In (welcome wagon), my sim went and stood on the ground next to the porch, by the mailbox (two neighbours was outside the door on the porch). I changed the door opening direction (it opens outward by default), which made it possible to welcome two neighbours in while standing on the porch. I pulled the door inwards one grid slot; that changed nothing. I locked the door/unlocked the door; that made no difference. I rebuilt the porch making it 4 grid slots wide (the stairs too) and then the pizza could be taken.

Same locked door thought bubble from my sim when pizza was delivered. In addition to the previous reports' symptoms, I also tried locking the door to everyone but employees and household and the sim / then unlocking them all. No combos worked, always got the "door is locked" animation.

The only bug i've not been able to move past or find a solution for is the pizza deliver. I order a pizza. Doesn't matter if it is cheese, pepporoni, or hawaiian. The pizza guy shows up. sometimes two of them. 1 will walk past the house the other will walk to my door. I click on the pizza guy and click accept pizza. my sim will scream and have a lock thought bubble appear above his head and the current action will be canceled. At this point. If i enter build mode, the pizza guy automatically drops his pizza and will remain at my door for a while. But upon entering build mode. I have tried increasing my door steps, and changing doors. After each of these steps i have re-ordered a pizza with same results. ive tried restarting the game same results. Ive tried researching all of the forums to no avail. this seems to be a common problem with sims 4. When is this fix going to be applied?

Edit:

Sorry for necroing this, but the issue on the lot Lagoon Lookout in Sulani, with the stairs being too small; seems to apply when there is a fire as well and the islanders show up to put it out. They could not come in, as per the notification:

When I widened the stairs to 4 tiles, and started another fire; they could run into the house and put the fire out.
