G98 return issue was created by n_spect_r
I am running version 2.8, attached code and an image. This is not the exact part, but the basic idea. There is a clamp between the middle two holes.
I need to go over the clamp. The issue is the diagonal path on the first and second jump to 2 inches.

What are you expecting instead of the diagonal paths?

If they are interfering with the fixtures then maybe this could do the trick (moves those two diagonal traverses away from the middle ) :

Code:
(DRILL PATTERN) G55 G17 G20 G40 G80 G90 T1 M6 S2000 M3 G0 G90 X1.0 Y0.0 M8 G43 H1 Z2.0 (BEGIN DRILL SEQUENCE) G81 X1.0 Y0.0 Z-1.0 R0.25 F12.5 G98 X1.5 Y0.0 X2.5 Y0.0 X3.5 Y0.0 G99 X4.5 Y0.0 X5.5 Y0.0 X5.5 Y-2.0 G98 X4.5 Y-2.0 X3.5 Y-2.0 X2.5 Y-2.0 G99 X1.5 Y-2.0 X1.0 Y-2.0 G80 G0 Z2.0 M5 M9 M30

I expected a Z move to 2 inches before any X or Y move. Much as I get a Z move to .25 while in G99.
The issue is somewhat moot as the program is running in a Mazak and it behaves as expected. 
I edited the program to just the single jump.
