Sloped metal roof. bugs. solutions?

[Adam West]

1. mainproblem: i got a problem with sloped roofs. ive build in my 4k hours playtime a lot of buildings with sloped roofs and i never had problems.
not long ago ive build a huge building for my dinos. 15x 31 foundations. sloped roof.
The building is too small now and i made a building 21x 51. again with a sloped roof. this building is extreme expensive and took me and my mates up to a month of farm and construct.
when i destroyed the old building we use the metal for the new one. when i destroyed the sloped roof a lot of roofs just fell down. a lot of material is wasted. it had still a connection to the wall, but it broke all.
now i build the new one and used 25/26 sloped roofs from each side. in the middle is a big hole.
How can we fix this problem. also the roofs are extreme easy to destroy. just attack the wall and the hole roof if falling down. it snaps kida nowhere. and theres a big hole. anyone knows how to handle this problem ?

i have some other problems too.
Maybe bugs.

2. Since some updates wild dinos spawn in our base. even next to foundations. all over the map. in all bases we find dinos in bases. the radius for despawn is 1. rescources are not respawning. we place more and more foundations. it dont help

3. Beacons regular go down on ceilings when theres a building. (a hotfix a while ago)
Now they seem to stop everywhere. sometimes in the air. unable to open. sometimes on the roof. sometimes on a level in the building. on the foundation. or like im this screen. in the foundation. it was a red one with a ring. unable to open. (

4. i transported a lot of creatures with quetzal in the new building. on our tours there were problems of course. today a friend was dreaming and fell down the quetz (hungry -> unconscious). i got the quetz on follow. when i arrived all dinos were gone. but they were nowhere. they were back on the platform saddle ~30 min later.

5. we cant use quetz follow when on quetz. we are always stuck. even with same weight other quetz always cause stuck. argi argi and ptera ptera works fine.

6. baryonyx consume oxygen. but the oxygen is not going up again when out of the water. it got no oxygen value. what will happen when it is down to zero?

I'd be happy for some help. ))
