If you are having issues with your installed contracts expiring, you can now use the CLI to bump it with soroban contract bump --wasm .... ...
You'll need to checkout this PR:
https://github.com/stellar/soroban-tools/pull/775
Or install it using the following:
cargo install --git https://github.com/AhaLabs/soroban-tools --rev 09749b6be5188d8a68b9913748dfef291a4bd587 soroban-cli
soroban contract restore --wasm ... should also work in theory, but I'll have to wait 6 hours to test it.
