#4 Sprite Image (spriteid) returns -1 in Hardware mode

[swagIT]

Sprite image (spriteid) works in regular mode but in hardware mode
returns -1 for all sprites.

Is this a known bug?

'CODE BELOW===================

procedure traintest() 'checks next track based on current train direction
- returns new direction

repeat

dir = newdir
