Sent a reply via email, but thought it was relevant to post here so others could see it:
SRD Super Tools Engine and HUD Maker does not conflict with Odometer Gauge to cause crashes or softlocks as far as we can tell so you can use it safely for your game project. We did catch two small bugs where 1) HUD Maker can't find a window of a specific ID and 2) HUD Maker draws the TP Gauge on top of itself again. These bugs will be patched over in the upcoming update later this month. Hope this helps :)
