This problem has also been affecting me recently and its very annoying to deal with.
but id say you'd would have to unsubscribe for now (which isnt a problem as this mod doesnt mess with your save)
I havnt tried that yet so im not too sure if unsubscribing would work.
hope i am of some help

i tried it, doesnt work

what all mods do you have?

same here

a) you should rather be using this more recent RICO fork: Ploppable RICO - High Density Fix

b) unsub all mods, sub and enable only RICO HD fix mod, start a new test city and try to place your RICO buildings. Does it work? If yes it is not the RICO mod but something else conflicting with it. Add back other mods 1 at a time or smaller groups of mods, launch the new test city. Placement works = recently added mods do not conflict. Placement fails = the most recent mod or group of mods generates the conflict.

Тоже самое и у меня. Строится все кроме жилых строений.

Also check whether this applies to you... FYI reference from the Real Time mod:
"If you experience problems with plopping the growables (buildings become invisible or do not appear at all), change the construction speed to 100% in the mod's settings and it will work fine."

Na I'm having the same issue. The "High Density" fix as shown above is no longer there. Did anyone fix this issue?
