Repositioning multiple subplots - not all plots appearing

I'm doing multiple subplots (72 in total) over a 12 by 12 grid. I'm trying to plot them and then position them such that the plots are edge to edge. The problem I'm having is that when I reposition them some of the plots disappear. I paste the first part of the code below, I get to the eighth plot and then each time I add a new plot, the last plot disappears (eg, when I add p9, p8 disappears).

samps=load('data');
colormap jet
set(0,'DefaultAxesFontSize',10,'DefaultAxesFontName','Times New Roman','DefaultTextFontName','Times New Roman');

p1=subplot(12,12,1)
histogram(exp(samps(:,1)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 
ylabel('A_0','Interpreter','LaTex')
set(p1,'pos',[0.04,0.92,0.08,0.08])

p2=subplot(12,12,14)
histogram((samps(:,2)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 
set(p2,'pos',[0.12,0.84,0.08,0.08])

p3=subplot(12,12,27)
histogram((samps(:,3)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 
set(p3,'pos',[0.2,0.76,0.08,0.08])

p4=subplot(12,12,40)
histogram((samps(:,4)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 
set(p4,'pos',[0.28,0.68,0.08,0.08])

p5=subplot(12,12,53)
histogram((samps(:,5)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 
set(p5,'pos',[0.36,0.6,0.08,0.08])

p6=subplot(12,12,66)
histogram((samps(:,6)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 
set(p6,'pos',[0.44,0.52,0.08,0.08])

histogram((samps(:,7)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 
set(p7,'pos',[0.52,0.44,0.08,0.08])

set(p11,'pos',[0.84,0.12,0.08,0.08])
p12=subplot(12,12,144)

If you're setting all of the positions manually, then subplot isn't really doing anything for you. You might consider just calling axes directly.

axes('Position',[0.04,0.92,0.08,0.08])
histogram(exp(samps(:,1)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 
ylabel('A_0','Interpreter','LaTex')

axes('Position',[0.12,0.84,0.08,0.08])
histogram((samps(:,2)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.2,0.76,0.08,0.08])
histogram((samps(:,3)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.28,0.68,0.08,0.08])
histogram((samps(:,4)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.36,0.6,0.08,0.08])
histogram((samps(:,5)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.44,0.52,0.08,0.08])
histogram((samps(:,6)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.52,0.44,0.08,0.08])
histogram((samps(:,7)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.6,0.36,0.08,0.08])
histogram((samps(:,8)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.68,0.28,0.08,0.08])
histogram(exp(samps(:,9)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.76,0.2,0.08,0.08])
histogram((samps(:,10)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.84,0.12,0.08,0.08])
histogram(exp(samps(:,11)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 

axes('Position',[0.92,0.04,0.08,0.08])
histogram((samps(:,12)),15,'FaceColor','m','EdgeColor','none','FaceAlpha',0.8) 
xlabel('$\gamma$','Interpreter','LaTex')

And Walter's right. One of the things that subplot does is clear other axes out of the way for you. That doesn't seem to be a feature in this case.

You effectively must create all the subplots before you move any of them. subplot() is defined to look for any axes that would be overloaded by the new subplot, and it deletes those existing axes. The area overlayed would be based upon OuterPosition, not upon Position, so you cannot easily figure out whether two axes will overlap based upon Position. So you need to create everything and then move them around, since moving them after has no risk of deleting the existing ones.
