Infinite Loop - While True [Python]

Running into the age old problem of the infinite loop...

Writing a text adventure game and have the game mechanics down; map and movement around it. Running into an issue with an infinite loop when I try to implement the other functionality - take items etc.

Below are 2 snippets of the code including the initializing variables, movement code, and the next stage stuff. Below the "......" are where the issue is.

All indentation is aligned as seen.


print("Welcome to this most intrepid" + game['name']
+ " your goal; should you dare to continue... is to" + game['goal'])
star_loc = int(game['start'])
curr_loc = star_loc 
character = {'inventory': [], 'location':curr_loc}
x_loc = 1
y_loc = 2
command = input("You are " + map[curr_loc]["desc"] + ' what next? ')

while True:
    command_parts = command.split()
    cmd = command_parts[0]
    print(cmd)
    obj = command_parts[-1]
    print(obj)
    #move around map
    if cmd == 'move' or cmd == 'go' or 'hiddenpath':
        #handles movement on the X plane - East, West
        elif obj == 'east':
            if x_loc == int(game['xsize']): # use the x size the game dict instead, compute the x and y 
                curr_loc = curr_loc - 2
                x_loc = 1
                y_loc = y_loc
                command = input("You are " + map[curr_loc]["desc"] + ' what next? ')
            else:
                curr_loc = curr_loc + 1
                x_loc = x_loc + 1
                y_loc = y_loc
                command = input("You are " + map[curr_loc]["desc"] + ' what next? ')
        elif obj == 'west':
            if x_loc == int(game['xsize']) - 2:
                curr_loc = curr_loc + 2
                x_loc = x_loc = 3
                y_loc = y_loc
                command = input("You are " + map[curr_loc]["desc"] + ' what next? ')
            else:
                curr_loc = curr_loc - 1
                x_loc = x_loc - 1
                y_loc = y_loc
                command = input("You are " + map[curr_loc]["desc"] + ' what next? ')

.................

    if cmd == 'exit':
        print('Goodbye')
        break

    if cmd == 'inv':
        print('You are carrying')
        for item in character['inventory']:
            print('', item)
            continue 

    if cmd == 'goal':
        print(game['goal'])
    else:
        continue
    
    if cmd == 'take':
        if obj in map[curr_loc]['obj']:
            print("You take the " + str(map[curr_loc]['obj'][0]))
            map[curr_loc]['obj'].remove(obj)
            character['inventory'].append(obj)
        continue

Major drag... └[∵┌]└[ ∵ ]┘[┐∵]┘
