Summary

When setting base-speed to a float value less than 1 (like in case of the "child" agents), the model behaves as if the speed is 0 — agents do not move. However, when base-speed is set to 1.0 or higher, agents start moving as expected. This suggests that base-speed is effectively rounded down or treated as an integer internally, even though it accepts float input.

Steps to Reproduce

1. Set base-speed to 0.001, and 0.9999
2. Observe agent movement — no movement occurs
3. Set base-speed to 1.0
4. Agents begin to move

Expected Behavior

Agents should move slowly when base-speed is set to a small positive float. There should be a noticeable difference between 0.001 and 0.9999, and both should result in slow but non-zero movement.

Actual Behavior

Any base-speed value below 1.0 results in no movement, making float values between 0 and 1 behave identically to 0.
