Do you use an acid stop bath? Are you sure it is mixed properly?
I've had terrible grain reticulation that resulted from too strong a stop-bath solution.

No stop bath, plain water rinse. Points for creativity!
That sucks, Richard. No matter how many stories of ruined film I read, each one pains me. They say voodoo only works if you believe in it. So.........?
I'm not a believer, but I can't think of any other explanation. I'm afraid to look in my closet though,in fear of finding a shrunken head.
Dont look in the mirror then. (Sorry, that was rude but I could not resist)
I am shure your problems will resolve themselves soon enough. I've had a few problems myself, caused by mixing Pyrocat MC in engine coolant instead of glycol.
I have seven rolls of Acros 100 that I was going to process in Pyrocat HD, ??????? do I do? Go with Rodinal? I know the temperature here is getting cold and a container on the lower shelf is colder than one on a higher shelf in the darkroom. There is no 'one' room temperature in my darkroom this time of year.
Rodinal contains Hydroxide and that raises the potential for excessive grain as it softens the emulsion more than carbonate.
I don't use Acros very often but when I do I use Pyrocat HD and with no problems what so ever, and that's the same for other people as well.
Richard's case here is an unusual glitch, somethings gone awry. It may be he needs to monitor his water temperature, that the controller's not as stable as it has been in the past.
It's worth remembering that modern films like Acros and Tmax 100 & 400 have an inherent fine grain and so choice of developer has far less effect on grain size unlike older emulsions like Plus-X or FP4.
Grain clumping/micro reticulation is not a specific developer issue although high pH doesn't help, I've seen this with Xtol, and a it's small number of films that are more prone than others.
My house in the UK has no central heating so temperatures drop significantly where I process in the winter but I've not found ambient temperature to be an issue with any developer and in particular Pyrocat HD which is now the only film developer I'm using.

I developed a test roll of TMY in a fresh batch of Pyrocat HD and it is fine. I don't know, and probably never will, what went wrong with the previous film. At least all is good now.
Good that you managed to get it working.
Could it be that you by mistake have grabbed a different component when you mixed the last batch?
