I will look into this

Hi Cormax, I am going to need more detail. I tried this in my SP game, prior placed Murayama walls and Foundations appear to be fine. I recommend joining my discord (invite link in Description) where you can post screenshots and it will be easier to track this.

After the last Conan game update, all Murayama walls and foundations placed before the update are no longer visible and their colliders are no longer active, but I cannot rebuild the same object in the same location, as if the game remembered his presence; thus, the "function of replacing one object with another" acts as if the Murayama building objects were still present.

That sounds super odd. I would suggest again that you join my discord and post some pics demonstrating what you are seeing, error messages from game and possibly mod list.

all my workbenches were just destroyed after I placed Murayama ceilings. according to the repair hammer their stability is between 80 and 60 but according to the event log the benches on top of these tiles "lost stability".

Hi @hekili, sorry you are having issues. I suspect you upgraded from some other Ceiling to Murayama? There is a known issue where is the collision surface from the upgraded ceiling piece is sufficiently lower than the collision box for the original ceiling piece, then things atop may lose stability.

The unfortunate reality is that ceiling collision boxes are inconsistent and vary by a few cm between various build sets. In general not enough to cause issues but sometimes. When I made my build sets I generally set my collision box height for ceilings and foundations at 0.000 on the Z axis.

This was often too low as base game tended to be 2 - 4 cm above 0 and caused stability issues on things placed on them during upgrade. I went through and worked to raise my collision boxes slightly to try to get to a sweet spot (remember no consistency)

At some point I hope/wish that FC would align those to a standard 0.000 on z axis. An easy, known position. However until then I will not go through and update all the collision boxes again. It would just be a game of hit or miss and floating placeables.

Not the ideal answer, I know. But that is the technical challenge in place.

i'm having issues withe me and my thralls falling through the murayama foundations when they cross the seams/ edge of the foundations

Hi @Supertoast93, has been reported, I am looking into it. thanks for posting.
