Is it a model you made yourself? Or got off the internet? If so, I would say it's animation is not working with the blitz engine. That I can not help you with.
However, if it is a proper working unit with a proper animation I might be able to help.
1) Go to the units.inf and open it.
2) Scroll to the unit in question, the fat unit. 
3) Look for the following variables under it's ID=#:
1
2
3
4
ani_move=22,26,0.13
ani_die=27,33,0.15
ani_idle1=1,7,0.08
ani_idle2=8,12,0.08
4)Change the last number to 0's like this...the "animation speed" is now 0.
1
2
3
4
ani_move=22,26,0
ani_die=27,33,0
ani_idle1=1,7,0
ani_idle2=8,12,0
Now the animation should remain "still". If you do not have these variables under the units ID that is why you get an error "unit has no animation". You should also know how many "frames" the animation is. . .if 1-3 is MOVE 3-4 is DIE and 5-7 is IDLE and you use the numbers 10,12,0.5 it will probable throw the same error. . .cuz there is NO 8,9,10,11 or even 12 animation frame.
p.s. you may have to use something like 0.001 and make it so slow it "appears" still. A 0 or 0.0 may throw a error I never tested this.
p.p.s. If you want the unit to appear in the same moving position you can make them all the same "animation frames" like this:
1
2
3
4
ani_move=22,22,0
ani_die=22,22,0
ani_idle1=22,22,0
ani_idle2=22,22,0
