I have just sown brassicas and cabbage 2nd crop and hopefully a second crop of carrots today as well, in high hopes, at least we have some water now which we have been very short of (we are on a well here) I agree though, as you have your sweetcorn in modules you can’t lose anything by planting them out. I had a similar problem, I ended up in hospital for the best part of 2 weeks and everything romped away here too and a lot of my stuff was lost because of the heat and drought to modules not yet planted out. Mind you, got a few good harvests of beetroot, carrots, kale, cabbage, onions, garlic, courgette and squash which I had been able to plant out before I went into hospital.
Best of luck and good weather to you.
