It sounds like you may be having framework crashes. You'll have to reload your last save from before it started happening.

That worked TY

This is a problem that I have rn, if i go back to a save a moment later it disappears again. My theory is that the reasarch option for victory class star destoryes somehow does this. After the reasarch is done no new units are added as a recruitble option and after that it dissapers.

EDIT

It had nothing to do with the rearsch. However every time I go back to a previous save it's always around the same amount of time untill stuff disappears

Got the same issue, first i thought it was the research option for the venators, but it doesn't seem to be the reason. If I reload an earlier save it'll work for a short period of time but after about 5 minutes the build options are gone again.

Adding to this thread, Trying to use Hero Menus and research upgrades also doesn't work after a while. Have had the above issues as well, started a new playthough. Noticed the galaxy map pause doesn't always work, and the galaxy update text is very laggy, will update while the galaxy map is paused. Note: didn't have the problem on 1.3 or on TR 3.3.

I will give it a week and try again.

I just ran into a similar problem.

This bug happens in the middle of the 100 cycle. Rebooting to old saves does not help, because the bug is always repeated.

Same as ЖМАЛЬ

THIS.... explains alot of what happens with me too.... never thought of looking at the cycle number but 100 sounds right..... absolutely no navy allowed to be built after that....

Same happened to me, but it occurred when i got 100% senate approval during the new campaign
