Project mesh and Rectangle terraforming don't work in sdk 0.14

hello everyone I had serious problems with the sdk since the sim update 5

the first problem
the project mesh and other objects disappear after build the project

Before build package

After Build Package

the second problem
The next problem is the terraforming rectangle, when the value for width and length is greater than 200


the package is not built and the following error appears in the console

I must clarify I do not know if it is a bug in the sdk or that I made a mistake but everything worked without any problem with sdk 0.13, since version 0.14 I have not modified my project

If anyone knows the solution to these problems, I would appreciate your help

**PDT: **
I have already tried with the new version of the sdk but same error

sorry for my bad english
