[Bug Report] The block has wrong initial position in FetchPickAndPlace env

[ekkooee7]

​​First, thank you for developing and maintaining this fantastic robotics simulation environment!​​ The FetchPickAndPlace task has been incredibly valuable for our research.

In the FetchPickAndPlace-v3 environment from gymnasium-robotics, the block (object) sometimes spawns ​​under the table​​ instead of on top of it. This makes the task impossible since the robot cannot reach objects below the table surface.

What version of the MuJoCo simulator are you using and provide the seed where it fails? Thanks.

( Also, update the GitHub issue title.)

I use mujoco210. I do not set a seed in specific, the block always locates at the bottom inside the table where the robot can't reach. I tried to find where to set the initial position of block, but seems that it's set by the xml file which is not included in the repo

Did you ever figure it out? I am having the same problem with using mujoco 210.

FIX: Use version 1.3.2.
