I have loaded your save and I can confirm that your crash is caused by seeing more than 10 enemies, it's not a map problem.
Please try to avoid scouting too much and kill enemies asap.
If you know how, you can try updating my mod, it's fixed already.
If you don't know how, just wait for next version of PirateZ.
PS: the unit with cannon went unconscious because of the smoke inhalation.
