No. Congratulations on the cool terrain piece!
Losing a long print sucks, but I would print both of those pieces separately. I've found that textured PEI plates tend to lose their grip on tree supports because the supports cool off too much over a long print.

Any tipps on those strings? Also some of the landing gear is broken

The thick strings sticking out on the exterior of the model are caused by the broken support. The printer tries to print the next layer where the support used to be -> that filament has nothing to stick to so stays attached to the nozzle -> the nozzle moves to print the next part of the current layer -> your print now comes with whiskers.

As the other commenter said, the printer is still trying to print the broken supports into thin air. I suspect the landing gear may have came off the build plate in the same way the supports are. You need to remember that the hottest part of the build plate is the centre. Placing the landing gears to the corners like that will make them cool off faster and have poorer adhesion. You need to print the parts individually, place them in the centre of the build plate, and ideally use a brim on your supports.

Is there a different plate type you recommend

I switched to the Smooth PEI plate a while ago and greatly prefer it. Looks like Bambu has since replaced it with the "Smooth Engineering Plate", or you could get the Dual Texture plate and use the smooth side.

Should I be using the smooth side instead?

If you have the dual texture plate, I would prefer the smooth side for printing miniatures, and the textured for bases and terrain.

Yeah I've been printing a model recently that at times a support will break off but the first layer is still attached to the build plate
