In the core prop group can only be as high as 15

[HowardBaxton]

Line 467 of the Core script we find this line:
rezParam=rezParam | (quietMode << 1) | ((propGroup & 0x2F) << 2);

The calculation (propGroup & 0x2F) will only allow 0 to 15 group numbers, after that, they start over at 0 again, so prop group of 16 will become 0 and be sent to the prop plugin as normal prop, etc.

The wiki states the limit is 63 (https://github.com/nPoseTeam/nPose-V3/wiki/NC-Contents#prop).
Which do we want the limit to be?

You are right. It should be &0x3F to work with 64 groups.
With the current implementation we can use the group numbers 0-15 and 32-47. 16-31 will be transformed to 0-15 and 48-63 will be transformed to 32-47

Due to copy & paste the same wrong calculation is inside the prop script. So I guess the "hotfix" will be: Change it inside the wiki to 16. I will do so in a minute.

To use 0-63 groups. we will need nPose V3.11 or newer and the prop script V1.01 or newer. This has to be documented.
