Hello invisible, can you try clearing browser cache and Flash cache?
Also, please check your Internet speed. With the current quarantine situation, many people are at home and using Internet, and thus many Internet service providers are quietly lowering the quality of their Internet services for the each line (so that they can meet the increased demand), resulting in, for some cases, the game not getting the optimal playing condition for some users. I know the game itself is not busted, or run out of trophy and unique fish, since other players are still catching unique and trophies :=) but some users may experience their games not responding well sometimes, or other lower game performances because of the lowered Internet service quality. Meantime, I'll report to the programmer so that they can check it to make sure it's working ok.
And, just for the kick, can you tell me which fishing spot you are at now? (no need to list all the fishing spots you were during the last week, just the current location, so that I can possibly do the quick check on that fishing spot)
