Is anyone having a lot of trouble printing Build Plat 3

I keep having issues where those little vertical upside down triangles are breaking off the base plate. 

Im using an X1C and my door recently shattered. I’m wrapping it up with a towel but I’m not convinced it’s working. The new door should be here in a few days but I’m just curious is anyone is also struggling. 

I’m not going to talk trash about someone else’s designs, but this is a very challenging looking print so I’m just curious is anyone else has had issues with this one.  Build Platform 1 and 2 printed pretty well.
