0 tick speed removal

I’ve had a world for 6 years and it was made on a frozen ocean. I’m building a city and any time a block touches water ice forms. To prevent that I would turn the tick speed to 0 and it stopped the pest that is ice for a long time. Yet earlier this week I can’t set It to 0 no more. I’m sure there’s a good reason for it’s removal like bugs but my world is getting annoying with all this ice and it’s added an old chore to this project. If there’s some kind of option that could be implemented that turns off ice generation or at least a block that’s hard to notice at prevents ice from forming. OH EVEN BETTER make it so ice can’t generate on barrier blocks
