Terramite's (unintended?) collision change in beta

In the present Public branch game, A friendly Terramite's CollisionMask is 8928 when idle and 9952 when moving.

But in Beta branch, its 224 when idle and 1248 when moving, its doesn't the collisions with the OBSTACLES and SMALLOBSTACLES groups now, enable to move through walls and other obstacles.

This is a very disastrous change that has completely destroyed almost all the Auto Farms designed base on Terramite over the past year. Significantly reduced the practicality of Terramite.

I reviewed the relevant documents and found that there was no recent edit. This might be an unintended change? I hope this can be fixed because it's really disastrous.
